Frequently facing Navision Instance Error!!!!!

southindian

Hi Experts,

I'm frequently facing "No Navision Instance is installed" error. I do found a soultion by searching it in our mibuso website.

The soultion is as follows

1. Open SQL Studio
2. Double clicked on the "NT AUTHORITY\NETWORK SERVICE" user under "Security / Logins"
3. Selected "User Mapping"
4. Check marked the database I needed access to
5. And copied in "$ndo$navlistener" into "Default Schema" for selected database
6. And at last checked marked:
db_datareader
db_datawriter
db_ddadmin

But Initial days after installing the above steps,I never faced this error for one month. But now I'm facing it in daily basis.
Now everyday i have to run this solution before running the RTC. Can any body advice where I'm actually missing.! :-k

With love,
Vijay
