  Description: Faulting application svchost.exe_BITS, version 6.0.6000.16386, time stamp 0×4549adc4, faulting module qmgr.dll, version 7.0.6000.16386, time stamp 0×4549bd9f, exception code 0xc0000005

This problem occurs because the Background Intelligent Transfer Service (BITS) state files are corrupted. This problem stops the host process for Windows Services. This behavior prevents you from using BITS to transfer files.
