Login Issue with strange error message

navuser1

Dear Sir,

The End-users are getting the below mentioned error message during login into the NAV 2013 R2 System. But the other users are working on the same (nav) server without any issue. What is the reason ? This strange error message comes(not always) since last four to five days.




Kindly reply.


Thanks & regards,

1.) Make sure the Server is running.
2.) Make sure your Service ****2013R2 is running
3.) Make sure SQL Server is running and the config of your service is pointing towards it.
4.) Make sure you have the necessary rights in NAV

Also check if there may be any DNS issues on those clients.
Before all of that check the eventlog on client and Service for any further info.

Other users are working on the same environment while someone gets this error message.

And it is true that the someone is not always unfortunate(able to connect the server).
