BSOD with SMB Compression
I got page "fault in nonpaged area" BSOD in "srvnet.sys" with server 2022 when I enable smb compression and open a rar file with winrar from remote mapped drive with windows 11 client. so when will ...
I can repro this, although I used a 7zip file and got BAD_POOL_CALLER (in srvnet.sys). To be sure we're talking about the same thing, it's the client that crashes? Because that's what happened here.
These are my repro steps:
1. Enabled SMB client compression on both Client (build 22523) and Server (build 22518) using EnableCompressedTraffic DWORD=1 in HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters
2. Opened a file share in File Explorer from client via UNC path on Server, ie: \\client\share
3. Attempted to open .7z file on client's file share using WinRAR by double-clicking on the file in File Explorer on Server
4. Client crashed instantly
I added it to the feedback hub: https://aka.ms/AAfb28m
Also of note, after removing the EnableCompressedTraffic DWORD, the GSOD/BSOD does not occur.
