XP Domain Logon

[DataDave]

Hello All,
I just implemented a new XP Pro system into a SBS2000
Domain, all features of the Domain work, Shared Files and
Resources etc... except Outlook 2000 will not access the
exchange server. I get a Logon Error on the XP system, which I think has everything to do about the problem. But when searching Microsoft's Knowledge Base for a solution, It can not find the same error. Here is what it looks like...
Source: Useren
EventID: 1505
Description: Windows cannot load the user's profile but
has logged you on with the default profile for the system.

DETAIL - Not enough storage is available to process this
command.

Anyone have any Ideas, Thanks In Advance
Dave
