  • 1. View share folder in other PC only by typing \\PCname?
    From my laptop(with Vista) I have no problem to access or share files with my DesktopPC(with XP) but I can only access if I click Start & type \\PCname. If I click Start, Network I cannot see my XP PCname appear in the Network Window but If I type \\PCname in address bar than the XP PC name will appear in the Network Window. No problem at all to access or share files between my laptop and my PC. I just wonder why I need to type \\PCname? Why the name doesn't appear when I click Start, Network? Anyway to fix this ? Thanks However my XPPC are able to see my laptop name by Clicking Start, My Network Place but why the laptop name doesn't appear when I view workgroup computers ?Both of them have the same workgroup name.
  • 2. VPN identity on local network
    Howdy, I don't think this is a specific Vista-ism, may happen with XP as well, but noticing it most with Vista. I'm running Vista Ultimate. When I VPN into a customer's network my local resources try to connect using the VPN account, not my Windows account. For example. I VPN into Customer with username of Delphi and my machine's local items like Outlook, SharePoint, MS CRM 3.0, Visual SourceSafe, Windows Explorer, which all assume my Windows login of dlozzi are now trying to authenticate me with a username of Delphi. Some items like Outlook, SharePoint and VSS I can manually override and enter in the correct info. CRM and Explorer doesn't let me. I can see in Event View on my machine that CRM failed connect due to invalid credentials with user name Delphi. I cannot access my local network servers, \\Server1, due to invalid credentials and it won't let me enter any in. This is quite annoying. Is there anyway to keep my Windows authentication running for my local items? Thanks!! David Lozzi
  • 3. RPC server unavaileble
    Hi. I am getting quite desperate and pulling the little hair i have left :) as i have now had this eror message for a few weeks and simply cant find a solution I have 2 PC one is running Vista Ultima registrated, i will call new PC(64bit) and the other Vista Ultima trial base(32bit) i will call old PC. I can share my folders from Old PC in network sharing but when i try to share folders from new PC i get an error that RPC server is unavalible. I can see the computers from both PC,s in the network map but i cant open any shared folders. I have tryed "netsh winsock reset" and "netsh int ip reset" but the same result. When i installed Vista in the beginning it worked and i could share but over time i have installed different programs and i did not notice that the sharing got a problem so i dont know to what restore point i could go. I hope that i will find help here and a solution to the problem. I have been thinking on reinstaling Vista again but i think i will than need to reinstall all programs and games again, is there a way to re-install Vista or to repair the instalation and network? If you need any info please ask, any help is appriciated. Thanks. Finn
  • 4. Cannot Enable Media Sharing
    I am running Windows Vista Ultimate x64. I jump through the normal hoops, but after I enable sharing and set all the settings, it shows that media sharing is disabled. I found that "Windows Media Player Network Sharing Service" is not running. WHen I start it, it starts and stopps immediately, and the folowing event is logged in the System log: Log Name: System Source: Microsoft-Windows-WMPNSS-Service Date: 4/30/2007 1:16:06 AM Event ID: 14332 Task Category: None Level: Error Keywords: Classic User: N/A Computer: Description: Service 'WMPNetworkSvc' did not start correctly because CoCreateInstance(CLSID_UPnPDeviceFinder) encountered error '0x8002801d'. Verify that the UPnPHost service is running and that the UPnPHost component of Windows is installed properly. After enabling Media Sharing, if I open Media Player and select LIBRARY-> MEDIA SHARING, it displays a dialog box saying "Media sharing is currently disabled, either because the sharing service is not running or your firewall settings have changed. To restart sharing, you must first confirm your sharing settings." I have enabled all WMP sharing-related firewall rules, and when investigating the service, I found what I explained above. PLEASE HELP!
  • 5. XP/Vista Printer sharing on different workgroup/domains
    Vista computer 'Workgroup' is hooked up and set for file/print sharing, however laptop running XP (attached to domain) cannot access Vista printer. - Network is set to private - printer is shared, public folders shared - password protection off - windows firewall is the only firewall and I've tried it with and without firewall on - internet connection works fine on both vista and xp machines - When browsing the network, i can see the Workgroup from the XP machine, but cannot connect to it. it doesn't show any computers on the workgroup, only shows the workgroup. I've read the instructions and see that it is recommended that both machines are in the same workgroup/domain. This is unfortunately not possible to do in this case (work machine & home machine). Any ideas? Thanks!!

Windows cannot discover any computer or device

I am running Vista Enterprise (final version) in a domain environment I have 
turned on the Link-Layer Topology Discovery in local gp and domain gpo but I 
still get the error "Windows cannot discover any computer or device" I can 
browse in explorer to every machine on the network but it seems to want to 
communciate with

I also do not get a full connection to the internet in Network and Sharing 
Center.  I can see my domain and I can connect to the internet and other PC's 
but when I try to repair the connection from domain to internet I get a 
"Windows cannot communicate with ( the ping 
was successful but there was no response. I know this is because we are 
behind a Firewall but surely MS has thought of this and has a way around this?

Hmm, puzzling!  I don't have an exact answer, but perhaps there's something 
here that might give you some clues.

Not sure about the "cannot discover any computers" or "do not get a full 
connection to the internet in Network and Sharing", but none of  (well, none 
that I know of!) the Microsoft servers respond to "ping" requests, so the 
lack of response to ping from doesn't necessarily tell you 

Try another destination for ping, such as or

I turned on both those settings on my small domain at home (single LAN) for 
my Vista workstations and the "Network map" now displays and shows all of 
the Vista computers (before turning on these settings, I got the message 
that the network map was suppressed by default in the domain).  The actual 
"map" only shows "Vista -> Gateway -> Internet", but the other computers 
(including the Windows Server 2003 R2 Domain Controller) are listed at the 
bottom as "The following discovered device(s) can not be placed in the 

Have you verified that the GPO containing the settings is in fact applied to 
the Vista computer(s) using the gpresult command or the Group Policy Results 
wizard?  I assume you have a check mark in the "Allow operation while in 
domain" check box for both settings.

Also, check that the Network Discovery exception is enabled in the Windows 
Firewall configuration is Enabled.

What do you mean by "do not get a full connection to the internet in Network 
and Sharing"?  The only time I've seen that sort of thing (e.g. limited 
network connectivity) is when the computer could not get an IP address from 
DHCP, but then I would expect you wouldn't have domain connectivity either.

My router has a built in firewall and does NAT as well, so perhaps the issue 
is not related to the "firewall".

orry, I'm not familiar with "proxy" servers etc. Here's something to try,
if you haven't already, in IE, click Tools, Internet Options, select the
Connections tab, click LAN settings. There's a spot there for configuring a
"proxy server".

If you are in a Windows Domain, presumably the DNS server (often on the same
server as the Domain Controller role) is doing the nslookups for you, so you
don't need "Internet connectivity" from the Vista workstation itself to do

I'm going to be out of town and most likely newsgroup incomunicado for about
10 days.

Hey, future dwellers. If you've found this thread because you're getting
the "Cannot communicate with" error, I finally found
something for me that worked. Microsoft's 'KB937168'
( http://www.**--****.com/ ) describes a Winsock bug after
configuring Internet Connection Sharing, and gives a hotfix for it. You
have to request it, since it's not production quality yet I guess, but
they'll send you a link to it if you ask like the article describes.
This worked for me, and it might work for you, too.

2.Vista Computers Don't Discover other Vista Computers

I have two new Vista Computers, both running Vista Home Premium 64 bit. 
I am trying to setup sharing so that I can use the same printer and
share files.  However, when I type in the other computers
'\\computername' (file://\\computername) into either of the two
computers search boxes it says 'Windows cannot access '\\computername''
(file://\\computername).  Both computers have the same Network name and
have Network Discovery, File Sharing, Public Folder Sharing and Media
Sharing Turned on.  The Computer w/ the Printer has Printer Sharing
turned on.  Both Computers also have Link-Layer Topology Discovery
Mapper and Responder enabled.  I can't figure out why they won't
recognize each other.  My only guess is that my wireless router is not
allowing them to see each other.  I have a home network connected to a
wired router that one of the computers and a Linksys wireless router are
connected to.  The second computer passes through the Linksys wireless
router to get to my home network backbone.  Any ideas?


3.Vista computer does not discover XP computers

I have 3 computers on a wireless LAN, a Vista laptop, an XP laptop, an XP 
In IE click Network Neighborhood on the XP computers and they display and 
can access shared files on the Vista laptop, and on each other.  In IE click 
Network on the Vista computer and all it shows is itself.  All computers are 
in same workgroup and since each XP computer sees all the others there seems 
to be no firewall issue.  On Vista computer, Network and Sharing Center > 
View Full Map shows all three computers plus the router.

Seems like I've had similar problems in the past that self-resolved somehow. 
 Any suggestions greatly appreciated.

4.Easy way to discover device model via SNMP ?


I am writing a management software that would provide some
basic info about the device, monitor some preconfigured 
variables etc. I was under the impression that detecting
a device model would be as easy as doing an snmp query
of a correct oid (entPhysicalModelName). Everything worked
great for all of my cats: 2900, 3500, 2950, 3750 series,
it worked great for 1760, 2801, 3745, 3825 routers.
But when it came down to 7200 and 3600 series it was unable 
to detect the model. Doing an snmpget on entPhysicalModelName
for 7200 returned an empty string, doing an snmpawlk on 
. also gave no results. Ok, lets
try entPhysicalName, still nothing, and finally entPhysicalDescr
gave some usable results. With aironet APs even more trouble
entPhysicalModelName.1 is set but all I can see there is
garbage ? entPhysicalName is set correctly tough. The real
question here is there an esay way (the one that would work
for all cisco gear, well IOS based at least) to discover
the device model using snmp ?

5.Discovering DHCP linux device


I have built a small linux machine that I take with me to work on
customer's sites, but one thing I would like is a way to detect the
machine on their network.

If I were the systems administrator there, I could go through the DHCP
server logs and find it.  But I'm not, and it just seems a little
unprofessional to have to ask for help to find my own hardware.

I know I could sniff the traffic and look for DHCP transactions, but
this is (by and large) a one time event which means I have to be
watching while the thing comes online.  And it is again a little
unprofessional as it is quite cumbersome to be poring through sniffer
data to find my own hardware.

What I would do is write a script with netcat that broadcasts the
device's presence periodically, and have another application on my
laptop to listen for these broadcasts.  As long as we're on the same
LAN I should be able to detect those broadcasts, and then I will know
the IP to manage the machine.

I can create this script, but I'm posting this to see if there are any
linux projects already underway that meet my requirements.  I know
that my NAS (Infrant) uses a similar approach to managing those
systems, so something like that would do the trick.
