Hi,I have SBS 2003 with Exchange 2003 and having 75 CALS for exchange. My Domain and exchange are on single server. Now i around 40 computers including SBS server has joined domain and i have created around 60 users(Mail) on AD. Now issue is when people start system and try to connect to exchange then first some users (10-15 MAX) can login properly n in between server gives a warning that your licensing is going to be exceed.

Now i want to check the CALS detail in my server and how can i resolved this issue?Pls suggest.Thanks in advanced.Hukam+919971945500

Hi Hukam,Can you post all event logs related to licensing coming on your server with full detail? Looks like this is SBS 2003 issue rather than Exchange Server.You can check out below KB article if any method, described in it, helps in your.

Supplement: Yes, please use the right forum for this questionAfter spent some time to research, the following is something you can start to check:Please check the licenses from licensing console, which displays the total number of CALs that have been activated on the server and maximum number of clients that were connected since the last server restart. This provides a quick indicator as to whether CALs exceed the limitation Please check the value of Concurrent connections in the registry: a. Start->Run-> Regedit b. hklm/system/ccs/services/licensinfo/msexchangeis c. Check Concurrent connections, change value to the correct number of users(the correct number is the number of licenses purchased) If the display number in the licensing console isn't correct, you may try to restart the "License Logging" serviceReferences: Description of the License Logging Service in Windows Server operating systems Windows Small Business Server 2003 R2 (SBS 2003 R2) licensing FAQ
