visual studio - VCBUILD : error : TimeStamping Failed. Result = 80070020, (-2147024864) -

i using jenkins ci build c++ projects using msbuild , visual studio 2008.

i sign signcode.

lately out of blue, started receiving error: vcbuild : error : timestamping failed. result = 80070020, (-2147024864) [e:\jenkins\workspace\main\xxxxxx\yyyyy\aaa\aaa.vs90.sln]

i installed microsoft visual studio 2008 forward compatibility pack tfs 2010 recently, don't think can cause error.

i used process explorer monitor e:\jenkins\workspace\main\xxxxxx error lookup saying 0x80070020 error means process using file didn't see using it.

and not find in google.

could please help?

thank in advance.

thanks, theo
