The server principal "NT AUTHORITY\NETWORK SERVICE" is not able to access the database "DYNAMICS" under the current security context.

Hi All,

I am able to successfully create user by using eConnect. After creation update some information by using sql queries. 

At the time i am facing this problem.

 Master Data Base : DYNAMICS

Company Data Base: TWO

i am using "NT AUTHORITY\NETWORK SERVICE" to communicate to the sql server.

i pass the connection string related to TWO database.

By Sql server Throws an error 

Error : The server principal "NT AUTHORITY\NETWORK SERVICE" is not able to access the database "DYNAMICS" under the current security context.

Is econnect checks the user permission,Is econnect or Sql server check the permission on each action.

Pleas give some idea about problem.

Thanks,

Srinivasulun.
