Hello Friends.

I am facing a serious problem.
this is my code which connects with SQLSERVER 2008 using Classic ASP.

 connstring ="Provider=SQLOLEDB;Persist Security Info= False; server=myServer;     database=myDB; Network=DBMSSOCN; Integrated Security=True"
 set conntemp = server.createobject("ADODB.Connection")
conntemp.Open(connstring)

I am getting this error

Provider (0x80040E21)
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.

How can i tackle with this problem
