This all needed slight additions for the 10.0.37 dev vhd, because of SQL cert issues... Needed to put -TrustServerCertificate in a few places.
Ultimately, using the previous info and the TrustServerCertificate parameter, was able to get everything working properly in the HQ side of the latest vhd 10.0.37.
I am able to activate CPOS, but NOT MPOS. Just get a DA3001 generic error. Did anyone in this thread activate MPOS or Store Commerce successfully?
Edit:
Tried this twice, so not sure why this works, but open MPOS and attempt to activate... Get the DA3001 error. Leave that up.
Install Fiddler Classic, open WinConfig button, then check the box for Microsoft POS, Save Changes, flip back to MPOS and hit Retry. Immediately I get the login/authentication screen. Close Fiddler and finish Activating MPOS. No clue why this works, but I've tried it twice from a brand new 10.0.37 vhd image, and same result. MPOS hangs with DA3001, but the second I open fiddler and check the MPOS box in winconfig section, MPOS activates, and then I can close/remove fiddler and everything works fine. How odd.
