  • 1. Two vista computers can't communicate
    I have 2 vista computers. A while ago when i used them in a small network they were accessible. The connection is made through a small router. Yesterday when i was operating on one of them and trying to access the other it popped an error, something like "Can't access this computer, talk to your administrator, blah blah blah"(i am the admin). But no... instead i could access another computer that was running Xp... i'm really annoyed and confused. Hope u help me solve this
  • 2. Can't connect to VPN - The reason code returned on termination is
    I've seen this error posted, but have yet to see a resolution to it. I have no problem connectiong to this VPN on my XP machine, but my new Vista machine refuses to connect with the error message in the event log: "... The reason code returned on termination is 828". I've found out this is a timeout and I checked the idle timeout drop down and it was set to "never" so that seems unlikely to be the root problem. Anyone got any suggestions? Thanks, Bill
  • 3. publication service device host
    i recently had my laptop reformatted, before this I was able to access the small network I use using ethernet hub. Now I cannot find the server (or other computers connected to it) I can access the net and I have the microsoft publication service device host icon showing. All settings are as they should be. I have taken my laptop into a service company and they were able to find their network no problem, but I don't get the same when I connect via ethernet. Other computers on the network can connect. If anyone could help it would be much appreciated
  • 4. How do I enable DHCP on my network adapter?
    When I check the status of my network adapter, it says that DHCP is not enabled. How do I enable it in Windows Vista Ultimate? I'm trying to enable it for ICS to/with a windows XP Pro computer. The other computer (XP) is not auto configuring itself with the right type of network settings. (IP, Subnet mask, & Gateway) For instance: it will configure itself to use 169.254.37.72, 255.255.0.0 instead of 192.168.0.(2-255), 255.255.255.0, and Default Gateway of 192.168.0.1.
  • 5. STOP Sharing folders, files and subfolders
    I have a many GB of data that was copied to a Vista Ultimate machine to my home folder though rsync. All of the items copied came though as not owned by me and they are all marked shared. Although i am curious why they would not be owned by me, I think I have that corrected, but when I right click a folder and select sharing-Stop Sharing, it quits sharing the folder, but any files and folders are still marked as shared. Please help. Thanks jim

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 microsoft.com.

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 www.microsoft.com (207.46.19.30) 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 www.microsoft.com doesn't necessarily tell you 
anything.

Try another destination for ping, such as yahoo.com or google.com.

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 
map.".

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
that.

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 www.microsoft.com" 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 
desktop.
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 ?

Hi,

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 
.1.3.6.1.2.1.47.1.1.1.1.13 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

Hi,

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.

Thanks,

Paul
