Global catalog on old server we want to retire
We have an old server which is a DC which we want to retire and replace. I decided best practice before demotion was to turn it off for a week and see if having it off causes any problems. It didn't until yesterday when we needed to create a new user account in AD. Failed because the global catalog could not be contacted as the server was not operational.
I have since discovered that this server holds the role of storing the global catalog. Googled it and it looks pretty straight forward to move but there are very mixed opinions on whether it is actually required in a single domain, single forest environment.
Global Catalog Server...did you know!!! - Bink.nu
My question is, do we actually need it and am I likely to get any problems moving it (I play to move it to the server that holds all FSMO roles)
Thanks in advance for any help/guidance that can be offered.
