ArcMap Lost All Connection to SDE FeatureClass Layers

[ShaningYu]

Recently, I executed the ArcGIS Desktop Patches, which include:

• ArcGIS-1022-DT-GFSSO-Patch.msp
• ArcGIS-1022-DT-OCPU-Patch.msp
• ArcGIS-1022-DT-OSSLU-Patch.msp

After that, All of the connections to the SDE FeatureClass layers in my MXDs are lost and can't be repaired.  Anyone knows the approach how to fix it?  Thanks.

I fixed the problem by replace the SDE Connection using ESRI's procedure (Repairing MXD Data Connections ).  Thanks.
