problem with .ZUP

Hi all. I work with Nav4.00 (IT) on SQLServer 2000 with Terminal server. Sometimes it happens that user cannot connect and i have to delete file .ZUP to re-connect the session. is there some solutions to resolve this problem? at last i think i can force a session to open always with the same .ZUP file: it is possible? how? thanks.

In the properties set the startparameter ID=xx, where xx - as an example - could be the initial letter of the user: … servername=yy, ID=xx
