I keep getting a MSDTC error - event code 4198 on my storage drive. I am running Windows Server 2003. This device is only used for storage. My server just shuts down with no warning or error, except what I see in the Event log. One fix I found out was to replace or restore the comdes.dll file. When I try to do it, it tells me that it is running and is being used by another process. How can I do this without shutting down the system and fix this error. The device has no viruses on it and there are no other errors present. There is no low memory error, either. Please help. This just started a couple of days ago.
