I restarted the machines multiple times. The update did not appear to have any negative effect on the QBSM. I had a client computer without the update have no issues connecting to the company file and putting it in to multi user mode. Once I installed the windows update, the client computer could no longer open the company in multiuser mode. Removing the update from the client machines returned everything to working order. The current webpatch for QB is R9. This was applied to all machines involved long before the issue arose. I also used the update feature inside QB Desktop Pro 2022 and verified all installations were up to date. Only the windows update has any effect on the client machines connecting to the QBSM. If it is installed then the clients will not communicate to the QBSM when opening a file which prevents the use of multi user mode. If the update is uninstalled the clients connect correctly and can enter multiuser mode.
