Hello, since a half a year we found following interesting problem with word 2003 while opening a word document on a fileserver and have no solution. Prerequisits: - native Windows XP SP2 installation and all security patches - Office 2003 Professional SP3 and all security patches - any 3party Word-Plugin; We've tested it with - PDFMaker-Plugin (Adobe), VIS-Compact-Plugin (PDV) and the International Character Toolbar-Plugin (Mircosoft) - We've tested it with a Windows Server 2003 Standard based fileserver and a NetApp FAS based Fileserver. Now following SMB network traffic behaviour will occur "only" if you open a Word-document by the Windows Explorer interface -> e.g. by double click or "open" by the context menu: 4480 16:23:15.707217 10.96.101.45 10.87.34.199 SMB Trans2 Request, QUERY_PATH_INFO, Query File Basic Info, Path: \Software\_Progs\Windows\Installation 4483 16:23:15.721372 10.87.34.199 10.96.101.45 SMB Trans2 Response, QUERY_PATH_INFO 4484 16:23:15.721485 10.96.101.45 10.87.34.199 SMB Trans2 Request, QUERY_PATH_INFO, Query File Basic Info, Path: \Software\_Progs\Windows\Installation 4485 16:23:15.735547 10.87.34.199 10.96.101.45 SMB Trans2 Response, QUERY_PATH_INFO (this is an excerpt by Wireshark - sequencno,time,source,destination,smb-request) Depending on which plugin is installed you'll have the same SMB-request in this manner 30 to 250 times in average. We measerud also values of hundrets of the same SMB request. After then a document will be opened. This behavior cause a lot of unnessessary network traffic and an opening process can take several minutes! (max measured value is about 25min) We have about 1000 employees, ~800 people work over LAN and about ~200 work over WAN on different locations. Does anybody have seen this strange behavior too or similar experience? Thanks for anticipation!
