I have an WCF Application using BasicHttpBinding . Application worked successfully when database server was in the same subnet as the development machine. e.x. 192.168.xx.xx but, my network administrator has given given separate ip from another subnet
to database as 172.xxx.xxx.xxx. from then on i am getting
"the MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot
find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B) "
I searched it , but ,since the only change was the Ip , answers seems to be invalid, is there any restriction such this in WCF ??
Thanks in advance.

You probably do have a firewall issue or the (2) machines cannot legitimately see each other. In the latter case if the machines are on a separate domain this would fall into the hands of infrastructure to add a DNS value so the machines can see each other.
However this kind of stuff is really out of the realm of the ASP.NET forums and more along the lines of the
TechNet forums. I think the 1st article below will help you work through all the potential issues and get your problem solved. The others may offer some guidance as well:
Debugging Distributed Transactions: MSDTC network problems:
Communication with the underlying transaction manager has failed:
Another "Communication with the underlying transaction manager has failed.":
On the purely WCF side here are some things to check if the endpoint address ever changes as it may have in your case:
Hope this helps! :)
