February 2026 Patches - Break RPC calls to DC

[ASierra]

There have been reports that the February 2026 MS update kills the RPC call to the Domain Controllers for various versions of the UF agent. This results in an MSRPC call storm to all domain controllers over and over until it drains resources. Check your _internal logs for 

splunk-winevtlog.exe"" splunk-winevtlog - WinEventLogChannel::init: Failed to bind to DC, dc_bind_time=1579 msec

splunk-winevtlog.exe"" splunk-winevtlog - Failed to set properties for event; EventRecordID=16354 channel="Application" error=6

Fix: A restart of the UF service on the local machines fixes the issue.

Hello @ASierra ,

I don't see it in known issue of Splunk. Maybe if you are still having this issue in production, raise Splunk support case to get it fixed.

I hope this helps!!
