After DC Win2003 Svr cannot acces samba resorcess

[Krzysztof Witczak]

HI
 
Maybe somebody can help me or give me information where to find solution
for this problem:
 
Last saturday i've installed SP1 on DC with SBS 2003 controler
 
on monday nobody could access shares on smb - samba - fedora machine
 
net ads info returns valid infos
wbinfo -u and -g returns complated info
 
I' ve rm TDB files and again add samba computer to ADS - no problem
 
again all infos ok.
 
in samba logs I've such infos:
 
[date time] smdb/sesssetup.c reply_spnego_kerberos(175)
 
and 
oft
[date time] smdb/sesssetup.c reply_spnego_kerberos(265)
 

Username xxxxx is not valid on this system
