Hi,
We have upgraded from TS6.1(with SP2, on windows2000 with SP2) to TS6.5 but i am unable to log in into the Teamsite.Although i am able to see the Y drive as well as the login page for Teamsite.
these are the errors i am getting (which i can see ) ::
>> When i enter user name and his corresponding role(as a master) It returns me this error

"Cannot create session string"
>> When i look into the services it shows me the iwproxy service is stopped.When i try to restart this service it throws me one error which is i think is windows error and the code is 1067
I tried to run "iwproxy" from command prompt and it gives me this error
iwproxy does not have 'Act as part of the operating system' (SeTcbPrivilege) privileges.
These need to be enabled for user iwmaster(This is the user who is trying to access teamsite server and he is responsible for installation, the person who has installed this).
One starnge thing is also happening when i run the command iwreset -a , it shows me the successful execution of all the services related to teamsite.How can it be possible because in service window iwproxy service is down.this is what i am getting when i run iwreset -a
