Symptom
I opened Component Services and browsed to Computers and My Computer. When I right-click My Computer and click the MSDTC tab I run into an out of memory error message.
Resolution
This is because the registry on your server is pointing to a default DTC that no longer exists. To resolve this problem you need to update the registry with the GUID of the new DTC. To do this follow these steps:
- Open Services.msc and locate your DTC
- Notice that when you open the services properties you will see the GUID of your DTC in the Path to Executable field
- Document or copy this GUID
- Now open regedit
- Browse to HKLM\Cluster\ResourceTypes\Distributed Transaction Coordinator
- Backup this key
- Edit the Cluster Default Resource property and paste in the GUID you copied from the previous step
- Now attempt to access the MSDTC tab and verify the out of memory error message disappears and that your DTC is now listed under Default DTC.
Thanks for this post, fixed my issue!
