I repaired my Windows XP SP3, and now Vault can find the DMS on localhost. I'm using Inventor 2010, Vault 2010, and ADMS 2010. When I go to ADMS to attach the vault, it won't let me login with the normal "sa" credentials. I've never reset the password from the default. So, I can't browse to find and reattach the vault. Nothing shows on the ADMS navigation panels.
Login from Inventor gets this "can't find" message, as does attempted login to Vault, as does ADMS attempt to locate vault for attachment. I've not set up a password on Vault either, in this standalone installation.
