We have Windows 2003 SBS Server with 5 user licenses. It accepts maximum 10 simultaneous user connections. If 11th user tries to connect to the server, he receive a message that there are not available resources. I have the following setting in Registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LicenseInfo\FilePrint ConcurrentLimit = 10 When I change the value of "ConcurrentLimit" to 20, the server accepts maximum 20 connections. But after one hour this value returns back to 10. So I have to change this value from 10 to 20 every hour ! Also I changed the permissions of the Registry key to "Read Only" for all network admin users. But on the other day these permissions returned back to "Full control" and the value changed to 10. Can you please help me to fix this problem ?
