CRM using SQL database in an environment of small business often inaccessible with the following error message

Hello

This is my first time on this forum so bear with my ignorance!  I'll expose the background of my setup and then explain the error.

We have a small business with a server running SBS2011 and PC running Windows 8 and 8.1 connected to the server in a domain environment.

We use a CRM product called Emu Tall that uses SQL Server 2008 R2 on the server for the database and the PC run a local application that connects to this database.

On a daily basis, but completely randomly and sometimes several times a day, a user will try and open the application on a PC and get the following error message.

Could not load file or assembly 'Microsoft.SqlServer.SqlEnum, Version = 10.0.0.0, Culture = neutral, PublicKeyToken = 89845dcd8080cc91' or one of its dependencies. The system cannot find the specified file.

At first, I thought it must be a matter of waiting time as it seemed to happen every morning, but I've proved since that it occurs at any time of the day and is apparently unrelated to amount of users or idle time or something like that.

Here's another oddity that hopefully sheds some light on it. If I go to the server and open the CRM application on the server, it works very well since it is only the PC that have the connection problem.  In addition, as soon as I connected to the server of any PC can connect immediately (until it happens again later in the day).  I don't need to stay connected to the server, connect one time and close the session and he "fixed" it for a few hours for all PC users.

I contacted the CRM vendor, and they are completely confused and have no idea what to do.

We are trolling along at the moment with me opening a session on the server for launch launch whenever a user receives the error message but it is far from satisfactory.

A final observation is that it does not always.  It used to work fine.  The problem began just two months ago and seems to coincide with the increase in our user from 5 to 12 users license even if the CRM provider swear that it is nothing to do with the license.  They may agree; I don't know enough to argue the point.

Any help will be appreciated! I'm sure it will be a simple solution and someone there will know why and the answer immediately but is elusive at this time.

This issue is beyond the scope of this site and must be placed on Technet or MSDN
