There are two SQLServer instances in one of our servers,one is
SQLServer2000,the other is SQLServer2005,
now,i want to monitor both of them(SQLServer Instance),so i do as follows:
step 1: create a new monitor ,add SQLServer2000 in this monitor,it's
successful,and application manager can receive data from this instance
normally,so i can see the status of my SQLServer2000.
step 2: create another monitor ,add SQLServer2005 in this new monitor,it's
successful too,but,when i click "poll now" ,it show error as "error occurs
when collecting data from SQLServer server."

follow as the instructions "Execute the file MsSQLDebug.bat under
appmanager9\bin\troubleshooting "
the result is :
C:\Program Files\AdventNet\ME\AppManager8\bin
\troubleshooting>MsSQLDebug.bat 149.208.108.70 3622 SQL sa phoenix
MSSQL2005

so,what's the problem?
By the way,the version of my application manager is 8610.

I would be very gratefull for your  help.
