issues logging onto OWA from a laptop in another domain

[headrush]

I have an issue with OWA. I have a laptop that is a member of Domain1. I plugged it into another network in another facility called Domain2 and am getting an IP from a DHCP server on their LAN. I am logging onto my laptop under Domain1 with my cached information. Now when I get try to logon to OWA it wont authenticate me but I can jump onto any other computer on Domain2 and log on fine and access email via OWA. I dont get it. Do I have to enter the domain information on my laptop because I usually dont have to. Any suggestions.

THanks,
Headrush

I think - After like 14 hours your kerberos ticket is no longer valid.

Does it prompt you for credentials? If so make sure to use the domain name when you attempt to logon. Dan
