  • 1. Limited ablity to work with folders and files on network shares
    Vista Business This is a new issue and I'm not even sure that this is the proper group for it, but since the issue is with nework shares, I figured this is my best bet. - Users on a specific Vista computer, cannot rename files/folders or move files/folders on network files. Same users on other computers (both Vista and XP) can access same network shares and perform renames/moves with no problem, so this is definitely a local issue. - At the same time, the synch has stopped working on that computer (automatic sync of desktop and My Documents through a group policy), and I cannot find anywhere I can see why or change. No joy from Synch Center: No errors are given, just no synch. - Another symptom which may or may not be related - cannot save files from the internet (even to local drives). Again, this is a local access as same user, same files from a different computer can save. All these symptoms suddenly occurred a couple of weeks ago, and before that all was working just fine. I have no idea where to begin to look in order to fix. Thanks, Ofra
  • 2. remote desktop ip:port
    Hello I have a lan with 2 XP Pro pc behind a router with a static wan ip, I connect to them remotely with remote desktop. I have forwarded in the router port 3389 to 3389 PC A port 3391 to 3389 PC B From a vista pro remote desktop client, I connect to PC A without problem but I can't connect to PC B, as soon as I type IP:port it displays "syntax error" I also use this vista pc to connect to another server on a different Wan address and it works. from a xp remote desktop client it just works fine, it connects to PC A by typing IP and to PC B by typing IP:3391 Why can't I specify a port to use in vista remote desktop client in the form IP:port I really don't understand.... Thank you if you can help me! Marie
  • 3. Wireless home networking
    Can anyone diagnose this problem? I have three laptops I'm trying to network for file sharing. All are on the internet. That's not the problem. The three computers are as follows: Bob's computer is the main computer with and MS router. The other two laptops are my old one and my new one. I want to move all of my documents from my old laptop to my new one using file sharing. The network we currently have allows my new computer to share back and forth with Bob's computer. It also allows my old computer to share back and forth with Bob's computer. But it does not allow my old computer to share files with my new computer. Just imagine a triangle of three computers. There is two way communication between A and B, and A and C, but B and C are not communicating. I need to know how to get B and C to commuicate so I can get my files from B to C. Thanks to anyone who can help with this. -- Barbara Library Clerk

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
