  • Patch Lady – Networking issues and KB 4088875

    Posted on March 15th, 2018 at 00:11 Susan Bradley Comment on the AskWoody Lounge

    As Woody pointed out earlier today there are some reports of networking issues after the install of this month’s Server 2008 r2 and Windows 7 patch.  The issues are not widespread and they appear to be limited to two scenerios:

    Scenerio 1 – VMware.  As noted on a reddit post a new virtual Ethernet network card is installed/enabled after the update.  The side effect has occurred before with other convenience rollups and a workaround was previously posted to this KB and a script is provided to fix the issue.  It is not impacting all servers, it appears to be impacting virtual machines on VMware.

    You can see more threads here.

    Scenerio 2 – workstations.  This one is a bit more fuzzy and not clear cut.  I’ve seen reports where workstations with static IPs may be impacted with this update.  There are definitely enough credible reports of chipsets being reset and losing their networking IP addresses.

    Note that I’m seeing this more in businesses than in consumer/peer to peer settings.

    On my Windows 7 (my old machine that we keep around for older programs), I’m seeing this update unchecked:

    Which normally means that Microsoft is throttling the patch while they monitor issues.

    What is honestly a bit more concerning is this documented side effect:

    After installing this update, SMB servers may leak memory. Microsoft is working on a resolution and will provide an update in an upcoming release.

    If you run a file server, you may want to run tests and determine if you do see THIS side effect as that one may impact.

    More on this as I see issues.
