Good afternoon

I have a Virtual server (running on windows 2003 Virtual Server 2005 R2) that cannot access any network recourses via a UNC path. I can ping the destination server and using a web browser I can navigate to the recourse, but I need to map a drive for file access?

Do you have any suggestions?

Thanks
Heinrich

Are your 'external" machine part of a domain?
I'm guessing that they are and that the VM server has not joined the domain ... this would leave you with IP access to everything but not able to authenticate to any domain resources.

The external Machine is a domain controller and the VM servers are not part of that domain. If I try to add a server I get a message that the network recourse could not be located. The  network resource that I am trying to connect to is a NAS device that is also not part of the network just on the same IP range.

ok, I think you are running into a browse master issue ...
try using the IP address in the connection instead of a machine name ...
i.e. \\192.168.1.3\<this share>  
see if you can access it this way.
If this works then you either need to setup/configure a WINS server or add the server name(s) to the local lmhosts file on the client machine.

I have tried to use the Ip address instead of the machine name and I get the same error. I have tried using tools such as tracert and netstat, but I receive an error stating that the commands are not recognised. A further thing I have noticed is that the master server has 2 Broadcom network cards, but the VM servers are listed with generic Intel NICs. There seem to be some of the network config missing?

Thanks

Lets go back to the start ... your virtual machine, running inside of the host server, IS able to connect to websites on servers onthe main LAN.  Is this correct?  If so, then your NIC and the networking ARE configured and working.

So, lets go back to the actual problem ... you are not able to connect to another machine via a network share.

Lets see if we can narrow down specifics that would cause this ...
Something is allowing web traffic and pings but not network browsing ...
- Is there a firewall running on your VM server or the host server?
- Are you running NAT/PAT on the VM server?  This should still work but might cause a problem ... you could try using a bridged connection and assign your VM server a real IP address that works on your LAN.
- You have an IP stack installed in the network interface of the VM instance but not MS file/print sharing ... this would allow basic IP connections but not let you access MS network resources.

Check these and let me know how things are looking.
