[plug] Fedora changes in Samba ?

[Kai]

Howdy peoople,

I recently upgraded my Linux server from RH 8 to Fedora Core 1, previous 
to the upgrade I had no problems mounting and accessing samba shares on 
my Windows XP machine, after the upgrade I try to map the drives and 
authentication fails.

I've google'd and had a look at Samba FAQ's and the answers probably 
staring me in the face but I can't find a cause for the problem.

In case it was something to do with XP not wanting to behave properley 
with Samba I made these changes to my registry, but that didn't help.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters]
"requiresignorseal"=dword:00000000
"signsecurechannel"=dword:00000000

No changes have yet been made to my Samba config and no other changes 
have been made to the XP machine.

Currently runing samba-3.0.0-15 on 2.4.22-1.2115.nptl

My apologies if I'm forgetting any important information, but any 
feedback is appreciated.

Thanks

Kai
