[Samba] WinXP login/ file access errors

[michael]

I am having intermittent errors from XP clients logging in and accessing 
files on the server.
"Insufficient System resources exist to complete this request"

I suspect this to be a purely XP issue, but I would like to rule out all 
possiblities. I have done an extensive google and microsoft searches to 
no avail.

Server: Custom Kernel 2.4.22
	xfs filesystem on Raid5 (setup in EVMS)
	Samba 3.0.0 (redhat rpm install - running out of time to build my own)
	Dual 3Com 3C996c NICS bridged

Clients: WinXP SP1
	Dual 3Ghz Xeon
	3GB memory
	onboard Intel Pro1000 gig NIC
	All registry and Group Policy settings according to Samba-HOWTO Chapter....
	 "requiresignorseal"=dword:00000000
	"signsecurechannel"=dword:00000000
	Do not check for user ownership of Roaming Profile Folders - enabled
	CompatibleRUPSecurity = 1

Similarly configured Win2K machines have been purring along just fine
