ColdFusion 7 throws a file not found message despite it being there

Hello,

I hope you can help on this issue, I have several Windows servers running IIS6 that have there web site roots on a remote fileshare.

Now the site seems to run OK but what will happen once or twice a day is that ColdFusion will say its lost connection to its keepalive file which is a cfm file and then fails constantly until you restart ColdFusion.

The server connection is good and seems there is no connection issues, can you help with what this can be, this is a new solution and on the old solution it seemed to run ok in a similiar infrastructure.

"Error","jrpp-38","06/02/10","11:13:22",,"File not found: testconn.cfm The specific sequence of files included or processed is: \\fileshare\testconn.cfm "

The server is running Coldfusion 7.2 and i've found a few articles with people having this but no real solution.
