Question if you don't mind. I created a Mapped drive "use net z: \\192.168.1.3\share" and the same for map Y. The original folks had a map to the same folder for two drives but used it for different applications. The reason for remapping is window work-group no longer recognized the "server" name and we had to map out IP as a quick fix until we are able to get there domain up and running. All we had done the night before for the customer was install memory from 4 GB to 16 GB and created a VM for Terminal Stations. The problem solved, but upon reboot, found that the drives were no longer mapped out. I again preformed the command. It once again solved. again on boot-up The drive was deleted. I was onsite for this boot-up and found the command box open with text deletion successful. I checked start up file and found Mapdisk.bat. When I edited it, I found that it was a command to erase both mapped disks. I also preformed the same function thought the windows mapping function to no avail prier to searching the startup file. I have since deleted the Mapdisk.bat file and been able to boot-up without loosing the drives. The question I have is I did this on 14 PCs on one work-group network. This happened to all but 2 or 3 PCs, one was a Newer Laptop, one was a WIN 7 the rest were XP. By doing the net use command, would that cause the Bat file to be created and placed in start up. I know none of the users were able to do it and I know it was not there before I mapped out the drives, but as I said, it was on most of the PCs that I had mapped out after loosing connectivity to the server. Thanks for any information you may have.
