AB Tutor Random Connections

[wroberts]

Hi All,

 

We are currently experiencing some issues with AB Tutor, we have the program locked down so that staff can only control the room they are in, however sometimes when a teacher is demo'ing to their class via AB Tutor we get random occurences of this lesson being Demo'd to other classrooms "Randomly" they are never the same machines and the affect just 1 or 2 machines in the building.

 

I was wondering whether anyone had seen anything similar as I know quite a few people on here use AB Tutor!

 

Regards

 

Will Roberts

 

If i have missed any information out please let me know as i would really like to get this sorted !

Is your dns cleaned out? Are the a records up to date? Bit of a long shot.

We believe so yes, has anyone else seen this problem on their network ?

We use AB Tutor here, but only a simple setup on a USB stick and 32 Fizzbook netbooks.

Not seen the issue you describe, but not likely to given the simple setup we have. Sorry, I can't be more help.

Had this sort of problem quite a long time ago - sympton with us was that some PCs would fail to appear and some would appear from other classrooms. It seemed to be connected to problems with the DNS when the network was flaky. At the time my classroom (I was a teacher then - I am now trying to get a job as a technician) was all wireless and they had a habit of disconnecting and re-connecting and the DNS got confused.

 

I have seen this again with proper wired connection - again when the network is a bit wobbley - maybe check that out first

 

if not try flushing the dns cache and re-connecting the DNS cache and see if all the right PCs come up

Is scavenging set up in the dns service on the server

I have this as well ! we have DNS scavenging setup and working, the issues do seem to be dns related though. i asked support to take a look and they weren't wanting to get involved, i guess thats fair enough to a point but in my view if the product works on dns (which it does) i would expect a "recommended / best practice doc kb or something) if i work it out i will make one and post it

On the troublesome student pc find the ip. Flush the dns cache.Then do a nslookup for that pc. If all is correct flush the dns of the teacher pc. You write a psexec acript to flushdns on multiple pcs if needed.
