SBS 2003 Server Limitations

Situation:  End users are unable to drill down through "Entire Network", getting kicked back with error exceeded max users or something along those lines.
Setup:  SBS 2k3 R2 with 20 CAL's(16 users)

Question:  Is there a way to create a session timer so that sessions expire faster allowing users to access network resources via either drill down method or other ways?

If you have 20 USER CALs and only 16 users, you are not experiencing any sort of SBS limitation.  There's no such thing as a session time-out if users are logged into the domain.  Plus, SBS licensing doesn't work on a concurrent basis... CALs are assigned to each user account until that user account is removed from the domain.

Please look in the Server Management Console > Licensing, to make sure that all 20 CALs are showing.

Then, rather than providing an anecdotal description ("or something along those lines"), please provide the EXACT error message received.

Ok, exact error message.

"XXXX is not accessible.  You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.

No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept."

It's not a permission issue, the user has the neccessary permissions to gain access to what they're attempting to navigate to.

Is this whilst trying to connect to the server or a workstation? XP has a limit of 10 connections at a time by design.

Can you please post a COMPLETE ipconfig /all from both the SBS as well as a workstation?

Thanks.

workstation side i'm unable to provide at this time(that and it's not an individual workstation having the problem, it's systematic among all workstations on the domain and sporadic, sometimes it happens, sometimes it doesn't)

I wasn't suggesting that it was a specific workstation, but having a sample workstation IPCONFIG would have been helpful since I would guess that all workstations are configured similarly.  You could easily have gotten that using psexec (http://www.microsoft.com/technet/sysinternals/utilities/psexec.mspx).  But no worries... because your server's configuration needs to be fixed before the workstations anyhow.

First though, I wonder what the MDameon Connector is for?

Most definitely you need to change the DNS Server to list ONLY 192.168.16.55.  The External DNS Server IP's are entered as Forwarders when you run the Configure Email and Internet Connection Wizard (CEICW -- which is linked as Connect to the Internet in the Server Management Console > Internet and Email).

A visual how-to is here:  http://sbsurl.com/ceicw

Seeing this also makes me think that you didn't join the workstations to the domain correctly.  In an SBS-based domain, you do this with http://<servername>/connectcomputer.  If you didn't do that, then to correct it you should follow the steps I've outlined in http://sbsurl.com/rejoin to rejoin the workstations.

yes, it turned out to be an issue with WINS strangely enough.

Doesn't sound strange to me... WINS is still an integral part of any SBS 2003 setup.
