Hi, I think everything is working because repadmin doesnt show any failures. Why do you think your replication is not working? regards Thomas Paetzold visit my blog on: http://sus42.wordpress.com

You will see error 0x2105 if you have UAC enabled and are not running the command from an elevated command prompt. Can you confirm you either have UAC disabled or are using an elevated prompt?

We don't have any replication issues. A couple days ago, we had a logon script issue. Someone suggested us to check replication. The logon script is group policy issue and we fixed it. I posed here because the dcdiag and replication show those errors. We havent disabled UAC and the command is not running on elevated promptBob Lin, MVP, MCSE & CNE Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Setup Windows, Network, VPN & Remote Access on http://www.howtonetworking.com

Hi, I agree with Neil, please try to disable UAC and run the command from an elevated command prompt to see if we will also receive the error code. For details about troubleshooting AD replication issue, please refer to the following article.

Hello, as Neil Frick said, please use RUNAS Administrator to open the command prompt BEFORE running the command and then check again.Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.
