Unable to validate windows 2008

[xqiu008]

When I go under "Software licensing" ->
resolve now or go online to get genuine windows
I got this message:

"This pre-release version of windows has expired, to keep using windows, backup your files, and then install any released edition of windows server 2008 R2 Datacente."

I am 100% sure my software is genuine. I've done a bit of research on this error. I might have problems with my system time. However, my system time is also up to date.

Can anyone help me with this?
Cheers!

That version is the newest beta version. Windows 2008 R2 is in beta. Read http://computerhelp.forum/f35/windows-server-2008-r2-beta-download-279.html and follow the ink to download the beta.

More than likely you have a copy of the original Windows 2008 beta which is now expired for use.

I have an original copy Windows 2008 Std(Volume) but unable to validate using KMS ,where need 5 server to activate.Then I try to using MAK to activate but Windows 2008 says cannot validate via online. I only have 1 server Dell PowerEdge2900. I became fade up on Windows 2008,hate Windows 2008. I better go back to Windows 2000 server-no problem to create Active Directory,DNS, and update the OS.Windows XP client could join the domain without problem.

I hate what Microsoft done on new OS.They still want to monopoly the market in server and desktop by creating the problem to new user. I hope this forum could solve my problem on Windows 2008 server; I don't want to waste our money to invest in new OS.
