Server with issue is Windows Server 2003 R2 Enterprise Edition
DPM is reporting that "DPM encountered an error while performing an operation for C:\program files\vexira antivirus\server\temp\aa29n3f0.vbt (ID 2033 Details: The parameter is incorrect (0x80070057))"
The problem is that the file isn't there and I am not finding any open file handles referring to that file as being held open (did a search using procexp.exe for handles or dll strings).
The temp subdirectory did have misordered permissions when I checked them, but I told Windows to reset the permissions and verified that applications should have access to the subdirectory and it no longer complained about access issues.
Anyone else run into this issue before with DPM?
