hi friends,
I am upgrading windows server standard 2008 r2 to enterprise 2008 r2. I have purchased two windows server 2012 standard license through which i will use the downgrade rights to upgrade to 2008 enterprise.
after acquiring two licenses through VLSC i received product keys in the form of MAK(1) and KMS(1), i tried using the DSIM command to activate the license and upgrade to enterprise, however i am receiving the error 1605 invalid product key.
i am temporarily disconnecting my server from local lan to activate the license, but no luck.
Also my internet network is different from that of internal network.
thank you in advance
