Thanks Giles and Timo :-) So if I look at a different authentication mechanism say LDAP would it improve performance? There is currently a local AD in the network which I think piggy-backs off the parent companies AD for mail. If this is guarunteed to improve performance I don't mind taking the time to learn LDAP integration; though I must say it took me quite a while, several months in fact to learn NTLM and get it working - with very little or no help from anyone on any associated list :-( .
