AutoCAD slow when connect the network cable

[asos2000]

I am facing a problem when try to open AutoCAD,
AutoCAD opens very slow when connect the network cable, but when disconnect the network cable its open normally.

Its not only one PC but more than one have the same problem.

AutoCAD is loaded locally on the user's computer, right? The network is used for storing files and/or printing?

When did this problem first occur?

[asos2000]

Yes, right

when open autocad and in the stage of opening the acad.dwt it come 98% then hang the PC for 1 or 2 mnts then open normaly

but when unplug the network cable the autocad start normal and fast

and the same happen when i close autocad

And have you installed all service packs?

Could it be this:

not that reason because the delay happens when opening autocad not when accesses the network.

When was the last time you did a disk cleanup or a defrag?

Maybe AutoCAD is having a problem finding the network license location.
