Environment
Client for OES 2 SP4 (IR12)
Situation
After undocking a laptop, then redocking the laptop, network performance is noticeably slower. While file transmission over all protocols is slower, NCP performance seems to be particularly affected.
Resolution
Remove Cisco Umbrella security application.
Cause
The Cisco Umbrella security application, like other such products providing anti-virus and other security features, can affect performance due to the extra processing required.
