Windows 2003 R2 SP1 server not connecting to UNC path.

We are trying to connect to a UNC path using Windows Explorer on the Windows 2003 server.  I can connect successfully from my XP workstation to the UNC path.  When I log into the server with the same domain credentials as the workstation I am unable to connect using the UNC path via Windows Explorer.  It is not security as I can connect on the workstation.  This seems to be something on the servers as I have tried from several servers.

The UNC path is a SharePoint (MOSS2007) document library with all appropriate security applied.

What is the exact error you get when trying to connect?
does the server have the correct dns entry?
can you ping the other servername (ie is dns resolving it correctly)
can you simply browse to \\servername

Not near the computer anymore but from memory -
From withing Windows Explorer I paste the UNC path into the address bar at the top and hit enter, then the error appears in an error box with the following inside -
Windows cannot find "\\servername\division\library\reports"  Check spelling etc.....

I can ping the server name with no issue.  You cannot browse to the \\servername UNC path as it is a SharePoint document library, so the full path must be specified.  However, as stated this is achieved from the XP desktop to the same UNC path.

I have read some other posts also, and I do not have the Advanced IE security installed on the server.  So that is not the issue either.

Thanks for the prompt reply.

Does the error look like this one on this post:

The browser issue is related to netbios. Make sure you have netbios over TCP/IP on your machine, (not netbios over DHCP).

Also register your DNS records on the computer you are trying to access the share to:

To do this go to the command prompt and type:
IPconfig /flushdns
IPconfig /registerdns
Net Stop Netlogon
Net Start Netlogon

These issues are most likely related to netbios. Make sure Netbios over TCP/IP is enabled, not netbios over DHCP.

Let us know how things work after you have done this.

Another thing you should consider is ditching SP1 and upgrade to SP2. SP1 has a quirk in it that may cause intermittent communications. SP2 fixes a lot of bugs. Upon updating to SP2, reboot the server twice. Otherwise TS and RDP will not work right.
Check if the "WebClient" Service is activated/started on your W2k3 Server.
If not start it and try to connect again.

This service is disabled by default on servers machines.

Thanks Mike1234567890.  That is exactly what the issue was.  I started the Web Client service on the server I was connecting from and I could then use the UNC path to connect in Windows Explorer.

SharePoint uses WebDAV I believe which the Web Client service enables your to connect to.

Quick fix and great service. Thanks to all who replied in attempting to assist.  Much appreciated.
