hello.

I have the following environment.
2003 domain, all 2003 file servers
1 2008 r2 RDS (terminal services) server.

Out of the blue, the 2008 server can no longer access 2003 file servers via
netbios host names. This has happened to many different 2003 file servers,
not just one. A reboot always fixes the issue, but there is no telling how
long before it happens again. It has already happened 2 times today.

I can ping the host, and I can still access the server via IP address and
FQDN. I have disabled IPv6. Here is a technet forum explaining my exact
issue, but there is still no solution.

I appreciate anyone's help, thanks!
