I have several site-to-site vpn clients that continually loose connection to mapped drives and I don't know where to turn to solve this.

Clients are XPSP2 w/Novell Client 4.91 SP4, Server is NW6.5 SP7. VPN config is

WS -> SonicWall TZ190 -> Cable or DSL connection -> Cisco ASA5510 -> NW

On Server Display SLPDA responds

SLP LOOPBACK : v2 : ACTIVE : NSI1_Scope_Unit : IANA : 0 : 0ms
192.168.0.1 : v2 : ACTIVE : NSI1_Scope_Unit : DHCP : 0 : 0ms

Total Active: 2 Total Inactive: 0

On WS SLPINFO /ALL responds

Anyone have any idea on this. We've been trying for months to make this work. I've even had Novell recommended "experts" come out with no luck.

Please help

Thanks
