Cannot login more than one user through Windows 2008 TS

I am having an issue logging into both a windows 2008 Terminal Server and the Novel Edirectory with the Novell Client

The login seem to work fine if just for a hand full of people 7 out 20 logging in but when a bunch of users try to log in at the same time some are getting connected to eDirectory but the majority are not.
logging each user in individually and had no problems. It seems to be that if multiple people are logging in at the same time that the Novell client
only authenticates the first one.
I'm not sure if there is a setting that needs to be changed on the Novell client when it is being used on a Terminal Server or if there is some other fix.
I'm hoping maybe someone has seen this before.
