Hi

I am receiving the error message "The request to create a reliable session has been refused by RM Destination.  Server net.tcp://navsrv:7046/DynamicsNAV/Service is too busy to process this request.  Try again later.  The channel could not be opened."

Background : Users start login at 9am, Everything is running fine.  At about 11am, there are 80 users connected and working fine, now for new login attempt the above error pops up.  After about 15-20 minutes its resolved auto.  But this is happening every now and then which is an issue we are without clue.

Can you share any idea please. 

Version : NAV 2009 R2 (3 tiers installation)

CC users: 100

SQL Server 2009R2 Std

Server environment Virtualised - VMWare
