•Symptom – The client was unable to promote the Windows 2012 server named “pta_t30” as an additional domain controller in their windows 2003 domain t6.local.

•Cause – We were getting the error: Verification of replica failed. The forest functional level is Windows 2000. To install a Windows Server 2012 domain or domain controller, the forest functional level must be Windows Server 2003 or higher.

•Resolution – We performed the following steps so as to get the issue resolved:

– Ensured that the health of the Domain is good.

– Corrected the Time settings in the registry on secondary domain controller.

– The windows 2012 server named “pta_t30” was getting the IP address from DHCP so we assigned the Static IP address.

– Corrected the NIC binding and the provided order on “pta_t30”.

– Ensured that we are able to ping the domain and DC’s from 2012 server named “pta_t30”

– Raised the forest functional level to Windows 2003 and forced Active Directory replication.

– Ensured that we are able to promote the 2012 server as a Domain controller.

When computers both internally and remotely try to VPN into my server that is running Windows Server 2003 R2 Enterprise Edition, they receive VPN Error 800: The remote connection was not made because the attempted VPN tunnels failed.

Your windows Server 2003 R2 use to work 100% without any technical problems, and you have not changed any configuration settings on the server.

Troubleshooting:

We noted that only 3 VPN clients were able to establish the VPN connection, the fourth connection was encountering the VPN Error 800:

Resolution:

We needed to increase the number of available ports for the client remote access / VPN users, by going to open the Routing and Remote Access console. It is under the Administrative Tools menu > Routing and Remote Access, expand the RAS – right click on ports and then select Properties.

Select the WAN Miniport (PPTP) entry and then select the Configure button at the bottom.

You can then change the number of ports to the maximum number of VPN users you will expect. For example in our environment we changed it to 20.

OK, OK again – Restart the Server.
