[Samba] error messsage was: Named pipe not available

[Chris Jones]

I'm having trouble authenticating users. WinXP will authenticate fine if
accessed via hostname... //fileserver/share. Ip does not work.. ie
//192.168.1.2/share. Anything below winXP cannot authenticate. Nothing is
shown in error logs. wbinfo -t does not work.. returns the following errors.
A few hot fixes were applied to domain controlers as well as SP4. No changes
were made to samba server. net ads testjoin results ok. As well as all ads
commands seem to work fine. wbinfo -u and -g return the correct users and
groups. wbinfo -p works also.

Any ideas are appriated.

Thanks
Chris
