Can you install latest OMSA 9.4.0 and try it You can download OMSA 9.4.0 from below link [URL]
I just installed OMSA 8.5 on a Server 2016 system.  The installation went fine, but I'm unable to get in. It keeps giving me the login screen, over and over.  I enter my (domain) credentials, hit Submit, and it just brings the login screen back again. The system only has IE on it, so I haven't tried any other browsers; I'd prefer not to have to do that, due to the nature of what the server is used for. Has anyone run into this issue?  Can I change an IE setting to fix this?  Is an upgrade to a new version of OMSA necessary? Thanks in advance!
