Trying to copy a binary file (.exe) from windows server to windows slave make job hang indefinitely and slave appear 'offline'.

In this case, the only solution is to:

• net stop hudsonslave
• net start hudsonslave
• modifiy job so that it copies a text file (instead of the .exe)
• run it
• revert job modification, copying the .exe again
• run it

Then it works for some times again (.exe file can be copied) if starting jobs manually.

But at least the next morning (i.e., when job has been triggered automatically), the job is hanging again on the slave (during .exe is beeing copied). In this case, the slave appears 'offline'
