smb create andx request extrange file name

i have issues in my network, programs using mdb files are getting corrupt. examining with wireshark i see a multiple entrys like this:

NT Create AndX Request; Path: \my_clientA\2013:\005PebiesnrMkudrfcoIaamtykdDa:$DATA

NT Create AndX Response; FID: 0x0000; Error: STATUS_OBJECT_NAME_NOT_FOUND

NT Create AndX Request; Path: \myclientB\:Docf_\005SummaryInformation:$DATA

NT Create AndX Response; FID: 0x0000; Error: STATUS_OBJECT_NAME_NOT_FOUND

NT Create AndX Request; Path: \myclientC\2013\:\005QebiesnrMkudrfcoIaamtykdDa:$DATA

NT Create AndX Response; FID: 0x0000; Error: STATUS_OBJECT_NAME_NOT_FOUND

The entry with 005sumaryinformation sounds good but the other two entrys call my attention. Can someone help me to understand this logs ¿?
