This domain has been trouble free for about five years. Last week I uninstalled the old Symantec Endpoint Protection 12.1 and replaced it with ESET Endpoint Protection. For some reason all two out of five workstations were very slow for about 24 hours. It could have been the first scan that slowed them down.
Everything returned to normal except on one Pc, one of the mapped drives from this Pc to the server started being a problem. The drives are mapped from a user script (bat file) that runs in the Sysvol/domain.scripts folder on the server. I manually ran the script on the PC but it did not resolve the problem. A red X appears on the drive letter (I) so this morning, I remotely connect to it that PC and clicked the I drive. It opened up fine but still had the red X on it. I was able to create a test file in notepad and save it in multiple folders within the I drive
With the red X still there, I clicked Disconnect on the drive. It said it disconnected but when I tried connecting it, it said a duplicate connection was there.
This user needed to update an application that stores the executable, updates and data files on the server's I drive.
Attached is a warning she receives when trying to run the update which doesn't appear to run.I checked the error in the screen print below. I was able to open the entire path, find the update exe file and even paste a text file in the folder, so I know this user has update permissions on the folder.
I've googled the error message (0x800704b3 and found it m,entioned as a common problem) but have not found a solution to this issue. Your suggestions are appreciated.
