Hi Thank you for the reply, yes it is running. actually I am new to this environment (where I am working), there is a stage server which is in cluster, but thing is that there is only one node and the SQL Server is installed on this I was trying to configure DB-Mail so that I can get alerts through this but after configuring the DB-mail the SQL agent need to get restart. so, I thought of doing it from SQL Server Configuration manager. But I was not able to do so because I was getting this error.
My environment is Windows 2003 Enterprise edition and SQL Server is 2005 enterprise edition both or on 64 bit.
Please let me know where It went wrong.
Thank you in Advance.
