Concurrent logins for one user

I have an FTP site that was created under Windows Server 2003 IIS 6.0.  I created a generic user for login puposes.  I work for a construction company and we have about 70 subcontractors trying to log in at the same time with the same user name.  A few have reported that they are experiencing issues logging in.  How many concurrent logins can one user be allowed for an FTP site or for Windows Server 2003?

I think it is not the problem in number of concurrent users, but in number of Threads that IIS holds opened for file transfers (also for listing, viewing etc...). The default number of concurrent threads in IIS for FTP is 10. You can change this safelly to 20 or 30 by editing Registry entry for "MaxPoolThreads".

previous post was for older FTP, so I guess newer FTP 6.0 does not have these problems.

check under FTP server site properties, how many concurent connections you have allowed. Set it to 70 instead of unlimited.

I actually switched to another FTP program that monitors user information and concurrent connections so the answer to this question is not needed anymore.  Thank you for your responses.
