Today we released a general patch titled ArcGIS Mobile Server and client SDK Patch for ArcGIS 9.2 Server for the Microsoft .NET Framework that you can install on top of ArcGIS Server .NET 9.2 SP6.
This patch is a culmination of hot fixes and we felt that it was important we share these fixes with all clients that are still using 9.2 SP6 and cannot migrate to 9.3.1 in the near future.
Please see the link above for details on the patch.
