c# - ActiveDirectoryServerDownException when getting the current Domain on a Wireless network -


i have problem regarding active directory classes in c#. @ 1 moment in program, trying current domain user logged in using following command:

domain.getcurrentdomain();

most of times, works. when executing wireless laptop, gives me following error:

system.directoryservices.activedirectory.activedirectoryserverdownexception: server not operational.      name: "domain.ca"      ---> system.runtime.interopservices.comexception: server not operational.         @ system.directoryservices.directoryentry.bind(boolean throwiffail)        @ system.directoryservices.directoryentry.bind()        @ system.directoryservices.directoryentry.get_adsobject()        @ system.directoryservices.propertyvaluecollection.populatelist()    @ system.directoryservices.propertyvaluecollection..ctor(directoryentry entry, string propertyname)    @ system.directoryservices.propertycollection.get_item(string propertyname)    @ system.directoryservices.activedirectory.propertymanager.getpropertyvalue(directorycontext context, directoryentry directoryentry, string propertyname)    --- end of inner exception stack trace ---    @ system.directoryservices.activedirectory.propertymanager.getpropertyvalue(directorycontext context, directoryentry directoryentry, string propertyname)    @ system.directoryservices.activedirectory.domain.getdomain(directorycontext context)    @ system.directoryservices.activedirectory.domain.getcurrentdomain()    @ adt.adtools.computerisindomain()

in particular case, piece of code should work on account logged in active directory account, regardless of computer it's being ran on or if computer connected domain using wireless or wired connection.

does of knows answer problem or workarounds make work?

i solved problem. source of problem internal our business network. did couple of things :

  • set third dns address on main router points ad dns server.
  • on wireless network card, put prefered dns server ip of ad dns server , alternative dns server, ip of main router.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
