I have an unusual problem with a Windows Server 2003 (Standard x86) box.

It appears the machine will not accept connections to its shares (locally and from other domain member servers) by using its ip address in a UNC path. The error returned is: "no network provider accepted the given network path"

This is the case with the machine's ip address: \\10.0.8.x and even the loopback address: \\127.0.0.1

\\localhost does not work...

but using the hostname (fqdn or not) works: \\server & \\server.domain.local

The local windows firewall for this server is off, ping/rdp/other services respond fine using the IP address.

The following services are running and have been restarted:

  • Computer Browser
  • Workstation
  • Server

The server itself has been rebooted too. Event 8032 in the system log indicates that:

The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{29A6A925-AFB3-47E2-BA59-DDA086DEAE7A}. The backup browser is stopping.

The domain controller has not been restarted, no other servers have experienced this problem, yet there are a number of browser (8021) related errors in the logs on this server.

Does anyone have any suggestions? I would like to avoid rejoining this server to the domain if possible.
