  • 1. Workgroup permission
    Hi, Is there any way to select a user account on other PCs of the same workgroup and give that user modify permission on a folder? I need to give modify permission to a specific user on XP pro pc which is part of the same workgroup to use a folder on my vista business folder. Like when you pick a user account from a domain and give that user specific permisssion to use the folder. Med
  • 2. Sharing Problem Freeze Vista machine in AD
    I have a small home network -running Active Directory. I have several XP Machines and one Visa Business64. The problem occurs only on the Vista machine, and only when I am trying to access shares on that Vista machine. I can access shares on the XP machines, or the DC (Windows 2003 Server). I enter Network. If I click on the Computer Name (or expand) to display the shares, it displays them. But when I try to expland the share itself, I get an hourglass and the system freezes. Or if I click on any of the shared resources, the same thing (hourglass - freeze) happens. I cannot click start or open task manager or anything. Occasionally the Network Explorer window looks like it is tile-ing, creating numerous tiled instances. I have to press the reset button I've checked the local as well as doman controller Event logs and there are no errors or info entries at the time before the freeze. I've run Defender and done Anti-virus Scans. Neither turns up anything. I've checked share and ntfs permission. They're OK and, even if they weren't, it wouln't cause a freeze. I'm an SA for a large organization, running AD with only XP machines, and I'm embarrased to say, I've run out of ideas. I hope someone can help me figure this out.
  • 3. Sharing a drive
    I've got an external drive on a desktop running Vista that I would like to access wirelessly through my laptop which runs XP. I've been working on it in my spare time for months now and have reached my wits end. I'll try and put in as many details as possible in the first posting to see how far we can get... The wirless network is running through a Netgear router. Both computers connect to the internet flawlessly. The workgroup spelling is set up exactly the same on both computers. File sharing is turned on and the network is set as "private." The username and password are exactly the same on both computers. I am able to see the laptop from the desktop when displaying the network map but that's where it stops. I cannot access any files stored on the laptop from the desktop and vice versa. When I try to map the desktop's external drive from the laptop, it cannot be found. The drive itself is set to be shared, and I'm using the exact address shown in the drive's information window (e.g. //desktop/external). I'd be happy to provide any further details anyone might need. Any help at all would be GREATLY appreciated.
  • 4. No access to a shared drive on another computer - Computer inacces
    Hi folks, merry xmas to everyone :) I have a small wireless network with a vista premium pc and an older laptop with shared drives - that are normally seen on a different xp machine or linux stations. On Vista, I can find the laptop as it is in network, however, i can not "explore" it, view its shared drives. The help adviced to flush dns cache as i did on both machines to be sure, but i still cannot access the small laptop - vista is OTOH accessible from it. Has anyone experienced it ? I am happy for any suggestions. Thanks, Vladimir
  • 5. TCP/IP Properties blank
    Running Vista Ultimate on a Netgear ADSL router. I have a strange problem developed, I normally run on a manually configured IP address of 192.168.0.215, now when I go into TCP/IP properties, the IP and Subnet are blank. If I enter the address the PC connects but when I come back to look at TCP/IP properties, the information is blank again. I tried to change the address to 192.168.0.190, I still get the blank address boxes when I go back to look at properties again and an IPCONFIG/ALL shows me connected to both 192.168.0.215 and .190 as preferred connections. Any ideas ?

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
