Issue with WSUS after running June 2016 Patch

Problem: I normally patch WSUS server at the end. I ran a quarterly patch on WSUS server itself. Couple of hours after patching I found out that clients were not reporting to WSUS console. I have a GP to let the clients contact WSUS every hour.

On the windowsupdate.log on the client machines. The following warning was registered.
#Warning: Failed to find update with error code 8024008.
-Windows Update client failed to detect with error 0x80244008

WSUS server event viewer:

Event ID : 1310
Event Code : 3007
Event Message ; A compilation error has occurred.
Application Virtual Path  /ClientWebService
Error  BC31007: Unable to open module file 'C:\Windows\Microsoft\Framework64\v4.0.3031a\Temporary ASP.Net Files..............

Scouring the web, not close but got some clue that there might be permission issues.

Solution : Granted Full Access Rights to C:\Windows\Temp folder to the group IIS_IUSRS.

Lo and Behold, no new error 1310 reported in WSUS event viewer and clients started reporting to the WSUS console.

I am not sure whether the new .Net updates /patches changed something but the above solution worked.

vLAG from Brocade VCS LC to Cisco 6509

Just for configuration testing, I am creating single 10G FC vLAG from Brocade VDX to Cisco 6509. It is straight forwarded.

BrocadeSW:

interface port-channel 9
switchport
switchport mode trunk
switchport trunk allowed vlan all
no shutdown

Interface TenGigabitEthernet 5/0/48
channel-group 9 mode active type standard
no fabric isl
no fabirc trunk
no shutdown
lacp timeout long



on Cisco 6509

interface port-channel 9
switchport
switchport mode trunk
switchport trunl allowed vlan all

interface TenGigabitEthernet 8/4
channel-group 9 mode active type standard
switchport nonegotiate
no shutdown


Make sure port-channel 9 is up  and line protocol is up

show port-channel 10

Also make sure interface is up and line protocol is up.


show port-channel detail. Sync status should be 1 to show the link is functional.
