i had just upgraded to 2.5 nsm to be able to upgrade to 3.0. the 2.5 upgrade went well and and was working great . after i installed 3.0 on a new server and ran the upgrade migration utility, which did not pull policies, I can no longer login to 2.5. i have restarted the services, and the server without any luck. I have tried multiple id's that should work.
I don't remember if there was default password backdoor, if anyone knows let me know. thanks
