Been working with tech support for a bit on this but still no answers yet. I am currently running 2020.4 for NCM. when i go to add the repository through NCM settings for firmware upgrades i get " Unable to access to network share using specified credentials" When i go to add the credentials under network share settings to give ncm write access i get "Incorrect credentials on (orion server name)" I can use the same credentials from the poller to map a network drive to teh share no problem, the account has full control permissions on the share. I was able to lock the account out by putting a bad password in either setting so it seems like it is talking to active directory at least. I have verified I can use a local account on the poller and point it to a local folder so the basic functionality seems to work just not when trying a network share.
The only articles I have found so far were for error if you had incorrect credentials, which i can prove they work just fine from the primary orion server or any other windows machine on my network by mapping drives with the credentials.
