Hi,
For some reason recently some of the drive mappings are showing as Folders in our user My Computer views. Then they cant double click the drive to view - they have to right click and explorer!.
it does the same whether going through a login script or manual 'map network drive'
only main change i can think of is adding a IF NOT EXIST recently to stop some messages during login

thanks
lee

Is it only one drive or one group of drives? Are they a members of the same hardware/system? Is that situation is same on all computers or on some of them yes on others no? I had a simmilar situation few months ago. The problem was one of those malwere and user PC was infected.

its a few shares, but not all - but yes thinking about it they are related to the same server (other shares on other servers OK) - malwarebytes scan you reckon??

What software You are using to protect users/servers? Give it a try with malwarebytes on both client and server that is hosting them.

hi, ive this happen to a number of users. It was caused by malware, problem was the a/v cleaned the executable but left behind an autorun.inf at the base of the drive or share that needed to be manually removed and was a hidden system file, Once removed everything was back to normal. Hope this helps

malwarebytes was clean, i enabled system & hidden files and there was an autorun.inf at the share folder route(s) created in the last couple of months - so i moved them elsewhere (in case something drastic happened!) - but still the same. Reboot required??

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The XOaUSuF.exe is probaly gone as a result of malware bytes or your antivirus cleaning up but the autorun confuses windows explorer because it tries to launch the file and it doesnt exist. There is generally never an autorun.inf at the base of a share or removable drive unless the vendor of the removable drive puts one their for their software. Rebooting does sometimes resovle the issue but I have seen a problem as well where a mount point is created in the registry that needs to be removed. Search the registry on the affected machine for the autorun.inf string and if you find a mount point that matchs the share path you can remoe it. Ill try and track down the m/s article about it

Registry location for mount points should be

HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Explorer/MountPoints2

A quick google search had this link which talks about the same issue with the mount points problem

http://www.us-cert.gov/cas/techalerts/TA09-020A.html

For me its been about 50% of people have the mount point issue, usually just deleting the autorun.inf fixes the issues. Hope this helps
