WHEN COMING RPC ERROR

WHEN ERROR COMING RPC DURING SUBMITTING OF POINT OF SALE ACCOUNT
RUN THIS BELOW QUERY IN QUERY ANALYZER USE TREASURY DATA BASE
After many days of implementation of Meghdoot Enhancement many of our friends facing  problems. So I have decided to post the solutions again.

1) While doing submit accounts ‘Server not configured for RPC’
Solution: Run the following query using query analyzer (replace ‘server’ with your server name):

exec sp_serveroption @server='server', @optname='rpc', @optvalue='true'
go
exec sp_serveroption @server='server', @optname='rpc out', @optvalue='true'
go

Note: The above error is related to SQL Server configuration settings and not related to the application. (RPC is Remote Procedure Call).
