I have this cross-posted to the MIS board. Apologies if that's frowned upon!
Hi,
We have an issue where users making a change in SIMS (has occurred in assessment, lesson monitor, behaviour), take a long time to save and then get an error and closes SIMS. Often, users then can’t get back in to SIMS. Sometimes it gives them the reason 0 error (even though their .ini contains a timeout of 10000), but some times absolutely nothing happens when running SIMS (no log in screen is presented either).
Strangely, this error logging in does not occur on all workstations. We've also had instances where a user on a workstation can't get in at one point of the day, but can several hours later with no changes made. Some users can't get in on one workstation but can on another.
In the DNS under interfaces we have Ipv6, the IP for the admin server and the SLG adapter. We have found if IPV6 and the SLG adapter are unticked the issue seems to stop. However, we're not sure why this would be the case and we don't really want to keep them unticked in future.
To give you more of a timeline / summary of the events :
Everything was working on Monday. From Tuesday :
Workstations crashing
Network running slow
Happening several applications (This isn't just SIMS specific)
Everything seemed to work fine once all the users had gone home (reduced network load?)
Problem occurring on both wired and wireless workstations
Workstations stopping and starting to work with no changes made
Does anyone have any insight in to what could be causing this? Have logged a job on Capita but not having any luck with them so far.
