Do you use ip address instead of a domain name on all machines? Then maybe working ones connect differently to the network, have different dns settings? Error says that Spark tries to find domain name based on ip in your dns, which obviously doesn’t exist.

All pc’s uses th ip addresses, if I tick login as invisable then it works and if I un-tick use old SSL under advanced settings then it gives me incorrect password

This is weird. Maybe Invisible login code uses its own login code instead of the common one. As i’m not a developer, can’t really tell. You shouldn’t use old SSL at all. If it doesn’t work with usual SSL, then again, something is wrong in your network and setup. But it will be almost impossible to find out via forums.

I would try to setup everything correctly, with domain name, correct DNS entries, etc. instead of IP. Maybe it will help to overcome your network’s issues.
That’s my blog on setting it up correctly with domain name http://www.wroot.lt/wp/technology/very-basic-openfire-spark-guide-en/
You can find a part about SRV records in this video guide How To: Video on setting up SSO/AD with Openfire

Great thanks will give it a go and will let you know
