'Connection Failed' when connecting to local iMac
I am unable to connect to my iMac that is on the local network. When I attempt to connect using the Registered User creditials it failes and the following message is found in the Console log: "sharingd[368]: SDSharePointBrowser::handleEnumerateCallBack returned 2". The iMac also has OS X server installed, but that shouldn't cause any problems here. It worked fine a few weeks ago on another network. The only changes made was removing various shared folders that were added. I am able to connect to my MacBook Pro from the MacBook Air. Please advise, thanks.
iMac, OS X Mavericks (10.9.2)
