Hi I think the above links will help you in you issues because I checked your logs they all point to MSDTC

Didn't work too.

I have un-installed the DTC and re-installed. Stopped  and restarted it, on both, K2 and DB servers.

Just for testing Purposes make sure your K2 and SQL firewalls are disabled. if you can't set off the fire wall off, please open ports to allow trafiic between k2 and SQL

hope these links help

Did you make sure that you have all your service objects configured as your source server?

Do you have any screenshot you can share?

Hi Hussian,

Some things you can check or try on:

1. Check that the MSDTC settings on all servers are correct. If the SQL servers are clustered, make sure you configure the cluster MSDTC as well.

2. If the SQL servers are clustered, try setting the MSDTC authentication to "No authentication required" on all servers.

3. If any of the servers has multiple network cards, check the routing tables. Make sure they are running on the internet network that does not pass by any firewalls or have a properly configured firewall that allows MSDTC communications.

4. Use DTCTester or DTCPing to test the connections between the servers.

Good luck!

Hi!

Here are some facts and findings about the testing environment issue I am facing:

1. I am using a development box to deploy the solution. I will call it "Client1".

2. We DO NOT have a clustered DB on the test. Only a virtual SQL server. I will call it "Server1".

3. We have a virtual K2  machine "Server2" and a virtual Sharepoint machine "Server3".

4. There are no firewalls enabled on all the machines above.

5. I ran the DTCping tool on "Server1" and "Server2" and got the below error:

"Server1"

6. Attached is the configuration on MSDTS.

Thanks

Hi HS,

Did some googling and the error message generally points to blocked ports.

1. I know you have turned off the windows firewall, but is there a hidden hardware firewall in between?

2. Can you check your services.msc. See if "Distributed Transaction Controller" is started?

The following article may be useful in troubleshooting your error.

Hi!

I come to know that the DB server got out of ports (due to unknown reasons) , so I had to restart the box.

Thnings are fine now. Thank you all for your hints and help. :)

Cheers.
