Problem

Although login credentials are correct, launching a Lycia Desktop/Web app through secure instance fails with one of the following errors:

ERROR: Change user failed :error 1787

ERROR_NO_TRUST_SAM_ACCOUNT

This issue typically occurs when the computer on which you're running the Lycia app can't authenticate with Active Directory. To resolve this issue, use one or more of the following methods:

Click Start, right-click Computer, and then click Properties. Under Computer name, domain, and workgroup settings, click Change Settings.

  1. Click the Computer Name tab, and then click Change.
  2. Select the Workgroup option, and then type a workgroup in the Workgroup dialog box.
  3. Restart the computer.
  4. Repeat steps 1 through 3.
  5. Select the Domain option, and then type the domain name in the Domain dialog box to add the computer back to the domain.
  6. Restart the computer.
