Autodesk Land Desktop across WAN

Hi,
Ever since our company has located servers at remote locations, I am
experiencing a lot of problems while opening/closing/saving AutoCAD
files. After the "upgradation" to a WAN optimizer, I have had to deal
with significant delay/lag in opening/saving and transferring DWG
files. I searched net, and the only recommendation I could find was to
disable AutoCAD's digital signature. How do I disable AutoCAD's
digital signature?Are there any repercussions or drawbacks in doing
this?

Any help would be greatly appreciated.

Thanks

 

Here is a way to turn off the Digital Signature.

Right-click your AutoCAD icon and choose Enable/Disable Digital
Signature Icons.
Uncheck the box. Click OK.
Log off and back on again.

Thanks.
