Hi, I am wondering if some one could help me please or at least point me in the right direction for KMS hosting. I'm "trying" to setup 2 KMS servers for my organisation. 100+ server 5000+ PC's I've setup the AD groups (for cross domain licening) I've configured DNS with the SRV records (plus permissions) I've then run the following commands slmgr.vbs /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx slmgr.vbs /ato SLMgr.vbs /SPrt XXXX (where xxxx is our new port number) I have also downloaded and setup KMS for Office 2010 (which seems to be working) My problem being if I try to install our KMS key from MS I get the following errors "The Software Licensing Service reported that the license is not installed" for my Windows Server 2008 Std/Ent KMS B key and "The software Licensing Service reported that the product key is invalid" for my Win 7 - KMS key (I've checked,checked and checked again and this is the correct key!) After trying all my keys the only one I have managed to get on (besides offce 2010) is Win Srv 2008 R2 Data Ctr/Itan KMS C This is driving me crazy as it should be so simple (or maybe it's just I'm so thick) My server is Win 2008 R2 and I have registered it with MS. Thanks Taggs
