Issue:
After installing 10.2.3 I received the following error when selecting the Users option on the Spectrum Control Panel, "SPC-OCP-10036: Could not connect to the SpectroSERVER on FRA1VOPB02T. Either no user model exists or the .hostrc file does not permit this host to connect." The .hostrc file contains a + and the spectrum  install user is in the Spectrum database.
Cause:
The user logged in with windows as Spectrum instead of spectrum as the install user shows. Capitalization matters with Spectrum where on a Windows server the capitalization does not matter for the username.
Resolution:
Log out of the Windows server and back in as user spectrum (lowercase s) resolved the issue.
