| Description | Error accessing service control manager on EXCHANGE. OpenSCManager:5. (AvUMRSyncSvr:3920) |
| Event Information | Workaround/Solution: Workaround: 1. Uninstall Windows 2003 SP1 from the Exchange 2003 server. Once this is complete, the Unity server (Windows) must be fully rebooted. or Place the UnityMsgStoreSvc account, the account the AvMsgStoreMonitor service logs on as, in the local Administrators group on the Windows 2003 SP1/Exchange 2003 server. Once this is complete, the Unity server (Windows) must be fully rebooted. 2. If the Windows 2003 SP1/Exchange 2003 server is a clustered Exchange server, place the UnityMsgStoreSvc account in the local Administrators group for all nodes in the cluster. Once this is complete the Unity server (Windows) must be fully rebooted. 3. If the Windows 2003 SP1/Exchange 2003 server is a domain controller, it is not recommended to place the UnityMsgStoreSvc account in the Domain Admins group because this group has explicit denies that are the default on all Exchange Message Stores. Placing the account in that group will allow Unity to access the Services Control Manager so Unity will be able to "see" the Exchange server again but all mailbox logins will fail. Instead, do option number 1 and uninstall Windows 2003 SP1. |
