SYMPTOMS
A Point-to-Point Protocol (PPP) link may fail after successful negotiation if the PPP host requested fewer than 16 slots for the Van Jacobson (VJ) compression. The failure occurs when the Microsoft Windows CE .NET 4.2 client tries to use a slot that is beyond the range that was negotiated when the link was established.
CAUSE
During the Internet Protocol Control Protocol (IPCP) negotiations, Windows CE will issue a configuration request with a MaxSlots value of 16. If the PPP peer rejects (NAKs) this and then it offers a reduced value, Windows CE will resend a configuration request by using reducedlower value of the PPP peer. However, after the link is made, the Windows CE VJ compression will still use slots 0 through 15, in violation of the negotiated number of slots.
