Hi, I just want to say thank you in advance for any help/guidance!
A very long story short, I was having an issue with OWA not working and reporting that my exch-01 server was missing from AD. Upon some digging I noticed that the server was missing from "Computers" in AD, but I was able to re-join it to the domain and quickly resolve that issue. However, OWA was still not working and I noticed the exch-01 server is missing from the (CN=Exchange Administrative Group -> CN=Servers) folder hierarchy in ADSI. How can I properly add it back? Thank you again!
