I migrated (without a transition pack) from SBS 2003 to Server 2008 Standard (not SBS 2008) successfully and went from 10 users to 30. We purchased the additional licenses for Server 2008, but end users are intermittently getting "You are no longer connected to [server name]." and remote users are getting inconsistent access errors when they attempt to connect to the server "VPN error 721". Is this a leftover licensing issue from SBS 2003 on the server? Is there a limit on the remote VPN connections? Server 2008 isn't restricted by CALs, so where is the License Logging Service hiding? Any ideas?

Hello, starting with Windows server 2008 the license logging service was removed as this never worked before as expected from Microsoft and the recommendation was always to disable the service complete. For workstations make sure they use the new server as DNS server on the NIC only. Please post an unedited ipconfig /all from the new server and problem client. When is this message shown "You are no longer connected to [server name"? Please provide more details, if in the event viewer please post the complete event. Additional it sounds that the new DC is used for RRAS to accept the VPN connections which is not recommended for DCs, except SBS version. See here some details about multihoming and RRAS on regular server version DCs from Ace Fekay: http://msmvps.com/blogs/acefekay/archive/2009/08/17/multihomed-dcs-with-dns-rras-and-or-pppoe-adapters.aspx In regular domains DCs should do there basic job, AD/DNS/GC and that's it. All other services applications should run on member servers.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
