Thanks for the update, i just had a first case with this problem. Is apple informed about this (and is there a chance they will change it ?) ? Is it possible to get a workaround in future versions in case they don’t ?

The symptoms are that \\AFS is inaccessible and an examination of the %windir%\temp\afsd_init.log file indicates a memory mapping failure when attempting to load the AFSCache file. This problem is likely to affect any user of OpenAFS for Windows on 32-bit Windows with iTunes installed that set their cache size to be larger than 500mb. The problem: Apple updated the Bonjour distribution as part of the most recent iTunes update. Included in the distribution is a file called mdnsNSP.dll which is inserted into the process memory space of every application on the system that makes use of the WinSock APIs. This DLL permits Bonjour discovery services to be used as a DNS replacement automatically. Apple set an image base of (16080000 to 160A4FFF) which is smack in the middle of the 32-bit process data range instead of using a value around 60000000 as recommended by Microsoft. The work around: The Microsoft SDK provides a tool called rebase.exe which is used by developers to modify the base address of a DLL. The following operations can be used to move mdnsNSP.dll to the correct location in memory. 1. cd to c:\program files\bonjour 2. rename mdnsNSP.dll to mdnsNSP.dll.inuse 3. copy mdnsNSP.dll.inuse to mdnsNSP.dll 4. rebase -d -b 0x60000000 mdnsNSP.dll The next time the OpenAFS for Windows service is started the dll will be loaded into the correct range in memory. Unfortunately, it is likely that the next iTunes update will break this again. End users are also unlikely to have access to the rebase.exe command. The command "dumpbin /headers mdnsNSP.dll" can be used to determine the image base. The affected version of mdnsNSP.dll is 1.0.6.2.
