This is really weird: I have set up an existing Windows Server 2008 R2 (Windows 7 Server) virtual machine anew again, keeping drive D: which is my data drive. Same settings as always, everything the same... But now I can't save one of my files which it did save on the same machine yesterday night! What happens is that ... The Save As dialog opens when I'm pressing CTRL + S. (very strange) If I then try to overwrite the same file from within the Save As dialog, I get an Access Denied error. If I try to manually rename the existing file from within the Save As dialog, first a dialog opens, telling me that administrative privilegues were required to perform the rename action. Confirming this I get a UAC dialog asking me if I want to allow the current application to apply changes to the machine. If I try to manually rename the existing file from within Windows Explorer, I also get prompted to confirm administrative privilegues. I never have seen this before on this machine. More information: When right-clicking into my D:\ drive and selecting the "New" sub menu item, all I get to select from is "Folder". It is not possible for me to add anything else to any directory than Folder. When creating such folder, within that new folder the New sub menu lists all possible file types then. But only there. This is because my account has been added to the ACL of this folder with full access. What's going on? I'm a member of the Administrators group. Administrators have Full Access on that drive. I have set up this VM with this same configuration about 6 times now. This only once occured to me before. I formatted the D: drive then. But I don't always want to format the D: drive. What's going on here? The D: drive has standard security settings: Administrators: Full Users: Read What's missing??? Any help is appreciated. Regards, Axel Dahmen

You're the administrator, but maybe you are not the 'owner'? Try taking ownership. If that doesn't do it, I'm stumped too.If this was helpful, please vote by clicking the green triangle. If it solves the issue, click Propose as Answer. Thanks!

Thanks for trying to help. I've tried that several time, and again now... To no avail... I assume there is something wrong with Windows Server 2008 R2 setup. I have done this hundrets of times by now, never had a problem with this. But all of a sudden this VM gives me trouble... This is the second time this happened, so I suppose there is something wrong that might not just be an accident...

Bettertoday,An other option is that your file is in use by an other process.Can you try to check if the file is in use?This tutorial explains how you can check if a file is in use:http://ask-leo.com/how_can_i_find_out_who_is_using_a_file_in_use.htmlDid you try to disable your antivirus software or boot in safe mode?Kind RegardsDFTIM me - TWiTTer: @DFTER

Unfortunately that's not the case. It's the whole D: drive that's blocked. I have a second thread with this topic open because I didn't know where to post it best: http://social.technet.microsoft.com/Forums/en-US/winserversecurity/thread/b17859a0-51df-4fc1-92d8-eac9c36b04d4 It seems the problem is UAC! But I don't have a final solution yet about what to do now. I don't want to disable UAC just to access my D: drive. There must be some other setting bringing back the old (expected) functionality without disabling UAT... Any suggestions are very much appreciated.
