SYMPTOMS
Your Routing and Remote Access Service (RRAS) Server may stop routing
network between segments and you may receive some event log messages
regarding checksum errors from neighbors.
CAUSE
One of your neighboring routers has sent a packet containing something
other than ffff. When the checksum of a packet equals zero, which is
illegal, RRAS expects to receive ffff.
STATUS
Microsoft has confirmed this to be a problem in Routing and Remote Access
Update for Windows NT Server version 4.0. This problem was corrected in
the Routing & Remote Access Service Hotfix Update. You can obtain this
update from Microsoft's World Wide Web Site on the Internet at the
