Sage 100 User Password Works Only Once: Why the Second Logon Fails
An Administrator resets the password in Sage 100, the first logon works — and every logon after it fails with no error at all. The password did not change. Something on that workstation did.
On the Sage Community Hub, “User Password works only once” describes it exactly. In Sage 100 Premium on SQL Server, a user logs on after an Administrator reset, reaches company selection — then, after logging out, cannot get back in. The dialog simply returns to the logon prompt, with no error message.
Sage 100 Password Works Only Once: The Server Is Not Changing It
The obvious suspect is the stored password — and in this thread it was proven innocent. A comparison of the MAS_SYSTEM database before a working logon and after a failed one showed them identical: nothing on the server rewrote the record. The Administrator account logged on every time, including right after the failures.
The Clues That Point at the Sage 100 Workstation
Two details did not fit a password problem. The password mask showed far more dots than the password has characters — about twenty dots for an eight-character password — and the reveal showed a string of $ signs in the Sage 100 2026 logon control. A fault that follows one user, on one machine, after exactly one good logon, is not living where most teams keep resetting it.
Where the Resolved Answer Landed
The poster closed the thread himself: a full uninstall and reinstall of the Sage 100 workstation resolved it, on port 10000 — not the port 9500 the install had been using — and he suspected something in the registry that the reinstall corrected. Which workstation setting was wrong, and whether yours matches it, is the judgment call hiding behind the silent logon.
Frequently Asked Questions
Why does a Sage 100 user password work only once? In the resolved Hub case, the stored password never changed — the fault was in the workstation install itself, and a full workstation reinstall corrected it.
Should we keep resetting the password in User Maintenance? A reset that works once and then fails again is evidence, not a fix. Repeating it locks the user out of work while the workstation fault stays exactly where it was.
What a Logon That Fails Silently Costs
Every failed morning starts with an Administrator interruption, a reset, and one working session — then the same failure tomorrow. A workstation problem quietly becomes a daily support routine nobody questions.
