Hi,

Just to let you know we have identified what the primary cause of the problems we were experiencing.

The system uses PKI keys and was only ever tested using Win2k/XP, we are using Netware inhouse as about 35% of our clients are still using Netware, it was an incompatibility with the Netware client and the systems PKI Keys, mind you the errors produced didn't indicate this, I had to go back to first principles to work out what was going on.

The government department is presently calling in their contractors to look at the problem.

Anyway thanks for your help.
