Important Cross-Post: Red Alert–Avoid KB2855336 Rollup with NIC Teaming and VLANs

This is a quick post to bring people's attention to an issue with the very recent KB2855336 July rollup update for Windows Server 2012.

Hans Vredevoort over at Hyper-v.nu has just blogged about a possible blue screen issue you might encounter if you have the following in place:

• Windows Server 2012 Failover Cluster
• Windows Server 2012 NIC Teaming
• VLAN's with your NIC Teams

His advice is to hold off on this particular update until an update is released to avoid this issue. Check out his full post here:
