We traced some printing issues to this patch. The application I work with uses LPR to send the print jobs, bypassing any need to install drivers on the servers we use. All of the old printers worked fine, except some new HP’s were not printing Postscript files correctly. It would interpret it properly the first time, then just print the postscript message the second time. It was every other print job and was wasting lots of paper. We upgraded the firmware for the HP printers to no avail. After a few days, we removed this patch – KB984496 and now it works as expected. Something to look out for, could not find anything on printing and this patch, but it was the patch removal that fixed it.

For any one having problems after applying 948496, also disable RSS and/or TCP Offload on your NIC or NIC team. I have seen several issues where leaving RSS enabled on the NIC team (while off in the OS) was causing problems. Of course you can also turn SNP features back on if they were working well for you.

[...] It appears there is a conflict between that patch and the Broadcomm NIC drivers in our HP server. There's some general chatter about the patch here. [...]

Horrible! Applied this to my DC’s – HP DL360G5′s – both servers identical in every way I can see bought at the same time last August serial numbers only 1 different. The PDC is fine and happy – but every time I apply this to my other DC it totally looses all network connectivity forcing me to go to the machine console and roll it back – cards and drivers and settings are identical – NOT using RSS or TOE – I even tried downloading a fresh copy but the same result.
The machine it doesn’t work on has only 1 thin different it has a PCIe SCSI card for my tape system.
Crock of C***

Up to now I thought this patch does only disturb x64 machines. Maybe I may refer to my post “http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?query=KB948496&dg=&cat=en_US_d02fc761-3f6b-402c-82f6-ba1a8875c1a7&lang=en&cr=&pt=&catlist=&dglist=&ptlist=&exp=&sloc=en-us”

I would like to know on what server hardware do James, Chris and Seth have this problem.

I uninstalled KB948496 and OWA works fine now. Bad patch!!!

I think this patch caused my Exchange 2003 OWA stop functioning normally: OWA times out every 20 seconds, and the preview pane requests log in too. Right-click to clean Junk E-mail shows error and those folders failed to update email counts. I noticed same folder update problem on my client Outlook too. Bad patch.

The fallout is bad if you aren’t ready. I use WSUS and when this puppy installed it took out my beta patch group. I had login to each server (which takes about 5-10 min with the now-crippled network adapters) and *disable* TCP Offload Engine and RSS. Tomorrow I will disable this on ALL my servers.

Great patch. Avoid it if you can.

The fallout….fixed a slow network issue, but caused the majority of my XP Pro clients not to be able to connect to server. I have been on tech support with Microsoft for hours and still no fix.

Caution: Make sure you have the very latest drivers for your NIC’s installed and be ready to back this out…FAST.
