Cause

MSDTC settings are configured incorrectly and not communicating transactional data to the server.

Resolution

Check MSDTC setup on both the Munis database server and the server where TPAR Administration is installed (typically IS server). The settings need to match between each server.

2. Double click Computers > My Computer > Distributed Transaction Coordinator
3. Right click Local DTC and click Properties
4. Click the Security tab
  1. Check Network DTC Access to enable
  2. Check Allow Remote Clients
  3. Check Allow Inbound and Allow Outbound
  4. Authentication setting should match between servers
5. If changes were made, click Apply
  1. Click Yes to restarting services
  2. Click OK
6. Repeat on second server
7. Once DTC settings match, recycle TPAR application pools in IIS

If the issue persists:

2. Check if firewall is permitting the traffic
3. Test MSDTC Connectivity Between Servers
