Error 1605: The specified product key is not valid for the target edition

September 19, 2017

Unfortunately, Windows Server 2008 R2 Standard Edition has limitation of 32GB of RAM. Too bad, if more memory is needed. When I have run into this issue, I have decided to upgrade OS to Enterprise Edition. We have VLK license that supports both Editions, so I did not expect any issues with this.

Cannot copy files during in-place upgrade to Windows 2003

August 1, 2017

It’s hard to believe but I have recently needed to execute the in-place upgrade from Windows 2000 to Windows 2003. Nothing special, but in the middle of the copy process the installer threw out the error:

Setup Cannot Copy the File Cmprops.dl_

I could see the file on CD, but could not copy it. OK, I ignored the message and immediately got another one about the next file. Well, the setup was cancelled.

July 18, 2017

From Windows 2008 to Windows 2012 the robocopy utility has been changed. Now it detects all files an “modified”.

After battling the issue on my own I have opened a case with Microsoft. Together with MS engineer we have found two potential solutions

Cleaning up the DFS errors

November 21, 2016

Some DFS-related errors, such as “Cannot enumerate namespace“, “Element not found” or “RPC server is not available” are related to the configuration issues in namespace. All  DFS components in registry, Active Directory and file system should be in sync. If they are not, the mentioned above errors happen. Pretty often it is easier and faster to remove DFS namespace completely and recreate it rather than to fix it. This article is about removing a DFS namespace and cleaning up all its components.

Changing IP configuration remotely

November 23, 2015

Once I received a request to fix an issue with MAC computers that could not access any shared folders on Windows file server. The Windows clients were OK. Well, the very first troubleshooting step is to log into the server. However, I could not do this. I got a message saying that domain controller was not available and my credentials could not be verified.

It looked like this server could not find a domain using the DNS servers in its IP configuration. But how to check and modify it?
