A synchronization server pair are displaying a red X and changes are not able to be committed to (60854)

Committing changes for a Mailbox synchronization job has failed and now the server pair displays a red X(This could also happen for Calendar and Public Folder Sync jobs).  Unable to save the config.ini to the server.  The service account is in the local Administrators group on the server and has full access to the share and full control to the agents folders via NTFS permission.  A connection can be made to the share on the server from the console, but a text file cannot be created in any of the folders.

When trying to connect to the \\server_name\c$ share the following error is received:

\\server_name\c$ is not accessible.  You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.

Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed.  Disconnect all previous connections to the server or shared resource and try again.

The EMWMigration.log file contains the following messages:

EMW:aeEMWGUIShared::CNetConnect::CreateNetConnection - Conection to \\server_name\IPC$ already exists.

aeEMWCommit::CmodConfigFiles::CreatePFS:Error: 75 - Path/File access error

Using the Net Use command reveals that there is a connection to the server at the IPC$ share from the console.

On the console from the command prompt run the following Net Use command:

net use /delete\\server_name

where server_name is the name of the server with the IPC$ connection.  If successful the command will return; \\server_namewas deleted successfully.

Note:  Using net use * /d will delete all open connections and may be a better choice than just disconnecting the server.
