Hi all, In Our environment there are around 18 Windows server 2003 Std Edition servers which we were planning to do an upgrade to Windows server 2003 R2 Std Edition. During the installation for the first time we had given the Product key of Windows sever 2003, now while running the upgrade it prompts for the Product Key, but does not accept the Windows server 2003 R2 product key. Please help Thanks-Sumanth

Hello, please contact Microsoft support, licensing questions are free and have the error message you get when trying to enter the key available. They will help you. Or do you mix some OEM and Volume licensing keys?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
