Hi, Could anyone tell me what this probelem is and if it's something that needs to be fixed..?? ntlm auth [3032] sending 'BH can't obtain challenge' to squid authenticateNTLMHandleReply: Error obtaining challenge from helper: 00D9440 error returned 'BH can't obtain challenge' This came up roughly about 200 times in the cache, before squid restarted itself and seems to have fixed it. No problems that i'm aware of.. I just don't know what above error means.. any ideas..??
