We are using transaction scope features of ASP.NET to manage distributed transaction for that we need to enable distributed transaction via following link:  

[The partner transaction manager has disabled its support for remote/network transactions](http://social.msdn.microsoft.com/forums/en-US/adodotnetdataproviders/thread/7172223f-acbe-4472-8cdf-feec80fd2e64/)

Its works well with SQL Server 2005 and Windows Server 2003 but when it comes to Windows Server 2008 server and SQL Server 2005 we are getting following error, still we followed the same steps provided in above link:

> 
> Windows Server 2008 + SQL Server 2005
>  + Network access for Distributed Transaction Manager (MSDTC) has been
>  disabled. Please enable DTC for
>  network access in the security
