Problem with Active Directory Services (ADS)

hi all,

Im facing a problem with ADS. Earlier my projects were configured with ADS in one of the server. Now we changed the server and moved in to different domain. I also changed the code to validate user info in ADS as per the new DOMAIN name with respective user and password details.

But Im unable to proceed further as Im getting an unspecified error while verifying USER info in new ADS domain.

When I run thru debug mode while verifying the user info under directory entry its raising an exception and when I look into the exception message its showing like Unspecified error and comexceptioncode is..some hexa decimal number..

may I know how could I solve this problem
Looking forward suggestion(s) from any one of U.

Thanks in advance
