ERROR_NDIS_GROUP_ADDRESS_IN_USE

ERROR_NDIS_GROUP_ADDRESS_IN_USE The requested group-address removal cannot complete because another component still uses the address. This is a shared-configuration ownership problem in legacy token ring support.

What to check

Track which component acquired the group address and do not remove it while references remain.
Coordinate cleanup during unbind and reset paths so reference counts cannot underflow.
Treat the condition as a local ownership conflict rather than a general network connectivity failure.
