Re: Slow DSL Connection SBS2003

Thanks for your reply, apology accepted this time! (smile) Just picking.
I don't see the ''Configuration''\''General'' in the ISA Management tool,
nor do I see ''Define Connection Limits'' . We're running SBS2003 and I
believe the ISA version is 2000. Could you be referring to a newer version?

Thanks again for your help!
