The system is Windows 7 Pro SP1 with all current updates. The software is used for finance/loan companies. The software uses a mapped drive (H) for its operations and the Windows 7 machine acts as a server in a client/server setup.
The software has a night transfer function where it copies the databse files (.mdb) to a folder where it zips them and transfers to home office using PC Aywhere.
During the copy operation the system halts before it can finish and comes up with an error that there is insufficient space in the folder to complete the operation.
The mapped drive is not accessible from explorer or by browsing the network
A google search points to increasing a value under the LanmanServer in the registry but that hasn't helped after upping it to 50
All the other functions of the computer and the software work fine until the night transfer operation is started
