Running NW 7.6.4 on a 2008 R2 server, with NMC server (7.6) running on a RH 
Linux machine. Co-worker who is my backup is unable to authenticate with NMC 
despite entering a valid user / password. They had upgraded their Java to 7, 
then they downgraded it to 6, but still unable to authenticate.  I am able to 
authenticate from my desktop using the same user / password. What to look for 
or where should I look for the cause ??

Thanks,
Paul
