A critical issue has emerged for users of Veeam recovery media following the installation of the Windows 11 24H2 update, specifically build 26100.3194 and higher.
This problem, linked to the February KB5051987 update, is preventing successful connections to Veeam Backup Servers and network shares during data restoration processes.
Users attempting to restore data using Veeam Recovery Media on affected Windows 11 systems are encountering various error messages, including:
- “Connection problems. An exception has been thrown by the target of an invocation.”
- “Failed to establish connection: no valid IP addresses were found.”
- “Unable to establish authenticated client-server connection. A call to SSPI failed; see the inner exception. The local security authority cannot be contacted.”
- “The remote procedure call failed and did not execute.”
These errors indicate a failure in establishing necessary network connections during recovery operations.
What Is Causing This?
The root cause is currently under investigation by both Veeam and Microsoft. Preliminary findings suggest that changes introduced in the KB5051987 update may be responsible for these connection issues.
To mitigate these issues, it is advisable to use Veeam Recovery Media created from a system running an earlier build of Windows 11, specifically build 26100.3037 or lower. This approach has been found to circumvent the connection problems introduced by the recent update.
When utilizing recovery media from a different machine, be aware that proprietary drivers necessary for hardware initialization (e.g., network, wireless, RAID controllers) may be absent if the recovery media was created on a system with different hardware configurations.
Ensuring compatibility of drivers is crucial for successful recovery operations.
Ongoing Investigation
Both Veeam and Microsoft are actively working to identify and resolve the underlying issue. Users are advised to monitor official communications from both companies for updates and further guidance.
Staying informed about developments is essential to ensure the reliability of data recovery processes.
