correct, but ONLY after they VPN , yet it does not occur in their homes

Sounds like the printer/scanner is having trouble finding the PC’s then…….

After connecting to the VPN they can ping other PC's and the printer , and I 
have actually confirmed it by adding  the printer using  a TCP port as opposed 
to the HP "discovery"  port, it will print fine but the scanning  continues to 
fail and they actually scan more than they print.



And as I mentioned when they take their laptops home this doesn't occur 
(granted it's not the same exact model HP but its the same software)

If the VPN is not doing split tunneling it will break that setup. Easy test, do 
a route print and see where the default route it pointing.  Or trace to an 
external public IP and see if it goes out your local gateway or down the VPN 
tunnel.



Can they ping the other PCs on the network when it happens? Sometimes it’s 
easier to see when you expand the list of symptoms.

soho environment,  5 pc's  using HP's native scanning protocol (twain WIA)



constant "scanner not found" from the pc's  rebooting the the pc's and 
printer/scanner it re-establishes connections- they do use VPN haven't narrowed 
it down yet as to whether or not its the VPN that "breaks" the scanning 
ability-- users claim that "at home it works fine with or without VPN"



looking to get a real "Canon/Ricoh/Xerox" into the office , as the current one 
is a consumer product



any thought's ?
