Hi Floks,

Presently i have facing below issue for one of my Client .

"The Server "DynamicsNAV71" was unable to process the request. Close the application and start again .

Server instance: DynamicsNAV71
User: XXXXX\XXXXX
Type: System.UnauthorizedAccessException
Message: Access to the path 'C:\ProgramData\Microsoft\Microsoft Dynamics NAV\71\Server\MicrosoftDynamicsNavServer$DynamicsNAV71\assembly\Page46_421.dll' is denied.

NAV Version : NAV 2013 R2 CU 51
NAV SERVICE Account :XXXX\NAV
SQL SERVICE Account : NETWORK SERVICE

1.We provide the full rights permission for both account for that folder.
2.We try to run both service with same Account but no output still Client having same issue .
3.We uninstall and re-install the NAV in that server.

Any Advise?

RE: System.UnauthorizedAccessException

Hi All ,

Thanks for suggestion. At present this issue is resolved .

Still root cause is unknown for this case , we create new VM for NAV app server then able to run the client. One thing confirm that It had nothing to do with permissions or Object Compilation.

I suspect that some windows patch causing this issue but not sure ...

Thanks

Regards

RE: System.UnauthorizedAccessException

Did you try to run client as the Administrator? and try to compile all the objects and restart the servcies.

RE: System.UnauthorizedAccessException

Hi, in times I had the same problem and the error gave with various pages or other objects. I don't know how to explain what exactly happened but what I do know is that when I compiled the object, the error would disappear. It had nothing to do with permissions. I think it had to do with the slowness of the server that was running the NAV service, the users were running NAV client from their computers in France and accessing servers in another country. The connections weren't the best so the RTC NAV client sometimes lost connection to the server for "seconds". I think that the problem was because of this. Can't garantee! Now we have new servers and changed the way they access. We haven't had any more errors of this type since then.
