I am getting this error while attempting to login into NRM on one of our

The server is NW 6.5 SP 5. It is in its own tree and has the master copy
of eDirectory.

I can log into NRM on other server but not this one. I can login to NRM
on this server from the GUI interface on the server, but not my
workstation. The ID and password I am using works in the GUI and in my
workstations NWClient for file access. In consoleOne there is no evidence
of failed login attemps in the intruder lockout property page.

I have tried changing my browser settings per TID 10094091, but that
hasn't worked.

Thanks for your help in advance.
