IP Helper problem I think

Hi all
I'm trying to configure my Cisco AP which is currently transporting my data network to also carry my voice traffic, I have set-up two vlans which are vlan 1 for data and vlan 2 for my voice.
My Swtich is configured as the DHCP server and my cabled phones are working well and getting IP's from the Switch however my wireless IP Phone is not and I'm getting DHCP time outs.
Below are my AP and Switch configurations and as you will see I have dropped in the ip helper address on a couple of lines which as failed to resolve my issue.

I just upgraded my iphone 4 to ios 6 using Itunes. After 1.5 hours all I have is an itunes graphic on my phone. It does nothing else and nothing seems to be happening anymore in itunes. Please help. I think I bricked my own phone and should have known bet

Please help. I think I just bricked my own phone. Despite worries after reading all of the rpoblems people have had upgrading their iphone to Ios 6, I used iteunes to do this to my iPhone 4. (I upgraded to the latest itunes.) Now after 1.5 hours of everything seeming to work OK, all I have is an Itunes graphic on my phone and nothing going on any more in Itunes. The phone doesn't shut down normally or anything. Suggestions? Should I just do a restore operation? I did back up my apps and pics.

Thank you. I ended up performing the Restore after I did an Update, and performing the restore solved the problem----I now have a functioning iPhone with all of my data, pics, and apps on it. Fortunately I made sure that I backed up my iPhone before I tried to update to iOS6. Man, what a headache though, and it sounds like I had it easy compared to some other horror stories I've read. I won't update my iOS on my iPhone again; i've learned my lesson. It remains to be seen whether iOS6 will be worth it :-)

I have a problem with iPhone is that I can replace it at points of sale in the U.S. because I bought from Saudi Arabia because the problem I think in the hard ware software worked more than 3 times did not fix

dears,
I have a problem with iPhone is that I can replace it at points of sale in the U.S. because I bought from Saudi Arabia because the problem I think in the hard ware I do resoftware more than 3 times did not fix.
Network also always missing.
I am living in KS Wichita. I hope you help me pleas.
Regards.

iPhone warranty is not international. You will have to return your
iPhone to Saudi Arabia for repair/replacement. Either take it back
yourself or send to friend/relative for them to take to Apple. Apple
will not accept international shipments for repair nor will Apple
ship repaired/replaced iPhones out of the country where the repair
was done.

Deactivation problem - I think

I have had Photoshop CS4 running on a computer since 2008. Now that computer has crashed so badly it won't start at all and it's so old it's not worth it to have it fixed. Thus I can't deactive CS4 on that computer. I have downloaded CS4 from the "My orders" page on my account and installed it on the new computer, but it won't accept the serial number and won't activate CS4on the new computer - likely because it hasn't been deactivated on the old computer. I have been on line in a Adobe service chat for more than an hour and been through two departments, but they ended up saying they didn't support that old program versions and linked me to this forum. Though I explained the problem five times, entered my personal details three times and the serial number for CS4 four times, I never felt sure they understood what the problem was. Can anybody here help?

I think it emits pretty specific messages about the number of activations exceeded if it fails to activate for that reason, so I'm guessing that's not the issue. Adobe absolutely has to support the ongoing activation of older versions you've purchased. They have called it a "perpetual license" after all.
Can you be more specific? Exactly what are you seeing happen? Screen grabs would be best.

Hi Ios 8.1.2 Should work on iPhone 4s / 5 You may have a bug Backup to cloud over WiFi Then Restore back to Factory Settings This will make iPhone as new. Use same Apple ID & you will get your Apps & Data back Do Restore over your WiFi. Cheers Brian

I am having the same problem I think. With mobileme you simply copy documents to the idisk folder and then synch. I cannot seem to sink that folder anymore. Any idea as to how I can simply copy folders to icloud and then access the MS Word and PDF file

Apple never bopthered to explain that this would happen
Your iDisk is still accessible after moving to iCloud in exactly the same way as before. Nothing is deleted until June 30th 2012.
, so I could easily have lost ALL of the files I kept on iDisk.
No, you couldn't. Firstly, nothing was deleted from your iDisk. Secondly, any files stored on your iDisk should never be your only copy. Even if your iDisk spontaneously combusted, you should keep local backups elsewhere.
Does Apple WANT people to move their storage elsewhere and stop paying Apple for it?
Yes. Apple doesn't provide such a service anymore, nor are you paying them for it.
Apple has made no effort to suggest remedies for the problem it has given iDisk users
They've provided instructions on how to download your files from your iDisk. What you do with them after that is your choice.

You might try starting up in Safe Mode: http://docs.info.apple.com/article.html?artnum=107393
If this works, it may fix your problem by itself since it forces a directory check of the startup volume.
If not, let us know what app you installed -- this may help us offer more specific advice.

Battery Problem i think !!! ... Please Help Me !!!

My iPhone 4 Suddenly Crashes Down as if the battery is empty .. when i try to open it he tells me to recharge .. i connect the phone to the recharger and it does Open .. but when i open it i check the battery i see that it wasn't Empty From the beggining

i just bought the mobile Yesterday ... and just have it Setup'ed and now it makes this problem !! ... is it a factory Problem ... or battery problem or what :S !

HELP! BATTERY PROBLEMS, I THINK...

Hey,
Got problems with my MacBook Pro battery. It started when I noticed it was taking a REALLY super-long time to charge...I would leave it plugged in over night and in the morning, it would still be at 63%. Then, it would say it was fully charged, so I'd unplug it and work on it, and it would just go dead, even though I had more than half a battery left (at least according to the status icon). This has happened several times, and it doesn't start back up unless I plug it in.
To make matters worse, just this morning, I spilled hot coffee all over the laptop and now it's really giving me problems...it's on and working but it will just go out even though it's plugged in, and it takes a really long time to start up again.
Do I need to buy a new battery or calibrate or ??????? Can I get it back to normal?

Oh, that's really bad. You are probably never going to get that machine to be back to normal again.
Those grains can get in between the circuits and any left over residue that dries on it can short the circuits on it.
Time to move the hard drive out of your machine and put it in a replacement. Hopefully your homeowners insurance will cover that. Never let food nor drink near your computer.

MacBook Pro 15" video card problems (i think)

Can anyone tell me if this is indeed a video card problem?
MBP 15" info (Dec. 2011)
Processor 2.4 GHz Intel Core i7
Memory 4GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
OS X Lion 10.7.5
This is what happened:
I use my mbp heavily because I edit a lot of videos with Premiere. I also use lightroom / photoshop alot + games. I also installed Parallels desktop late 2013. I don't know if that is relevant but anyway. Everything started late 2013 (a little after installing parallels actually) when there are moments when the audio wouldn't work and I couldn't adjust the volume. It would come back anyway so i didn't mind it. Then the fans were on high speed for little activity. After that the keyboard backlight couldn't be adjusted and wouldnt work. I ignored all of these cuz i wasn't troubling me at the time. In January i left for france to study - I use bike all the time and once stupidly placed my laptop on the basket going to school (rough roads). I had a class with html so I had to open Parallels, my teacher pointed out the fans and how loud they were. That day, parallels desktop said i must upgrade to windows 9 or it will restart every 2hours. I didn't of course. I didn't have time to.
After that (a few days later i think) my laptop would randomly turn into a black screen but it's still on (the power LED is on) I tried turning it off by pressing down the power button and then turning it back on. It worked the first time. During the first week, the frequency of it happening grew. It would do it almost 3 times a day. during that same week I tried to do an SMC reset. It fixed the keyboard light, fans and audio but not the black screen thing. It just keeps on happening around 1-3 times a day. It only happens when I'm using it btw, never when I just leave it. ALSO, after a few days, it would take longer hours to open my mbp again. I mean, the screen would turn black. i would turn it off, then on again. I will ONLY hear the hard drive moving but no startup sound and no grey screen and apple logo. nothing.
The following weeks after that, I asked a friend to help me out. He suggested that I install gfxCardStatus because he said it might be my video card. He instructed that I keep it on intergrated only. So I installed that and did what he said I thought it worked for a while because the black screens stopped happening (even when gfx keeps on going back to dynamic) BUT NOW, MY LAPTOP WOULD FREEZE (not turn black). I'd shut it down using the power button but it still takes me hours to open it again. Sometimes, I'd wait for the battery to drain because it would startup when i charge it (sometimes)
I tried doing AHT as well to confirm the video card problem, but the results are no problems found. I really don't want to replace my logicboard here in france. everything is more expensive here. ;__;
Today I uninstalled parallels to see if that might have had anything to do with my problem now but i think that's just wishful thinking.
Can somebody tell me if this is really about the video card? Thank you

Your appointment at the genius Bar in an Apple Store (anywhere in the world) for an evaluation is FREE, in warranty or out. Those guys put their hands on these Macs all day every day, and they are especially good at Physical and Power problems.
Ask them.

HELP! I think I have malware but can't find it...

So I've been searching for the last two days and I feel like I've read everything from DNS Poisoning to RootKit hacks but I can't seem to figure out my problem. Here's what I've been facing:
About once or twice a day, at random points, my browser opens a new tab and tries to search a long laundry list of random words, all of which are never the same each time. Some times, instead of using Google or Bing to search, it'll open up Mail, compose a message, not addressed to anyone thankfully, with another set of random words throughout the message. I've run three different virus/malware/etc. programs but none seem to have fixed the problem. I've tried Sophos, ClamXav, and DNSChanger Removal Tool, none of which have found anything. I've tried the Terminal cache clear and scutil commands, and although I have a gray DNS in my airport settings (192.168.0.1), I haven't had any other DNS numbers show up or be grayed out. I've also had a hard time loading web pages which has never been an issue. Could this be a problem with the wireless router that I'm connected to and not a Mac problem? (There's a PC on the network and my parents aren't very technological, meaning they could've downloaded just about anything thinking it was something they needed.)
Here's a screenshot of the problem that just took place a few minutes ago:
Any help would be greatly appreciated as I'm completed at a loss for what to do now. Thanks in advance!
-David

I doubt you have malware, spyware or a virus, since they are so rare on a Mac. But what I think you have is someone who has access to your MacBook Pro through Screen Sharing. I'll bet someone got access to your Mac, and set it up, especially since a local port is open.
Check System Preferences>Sharing>Screen Sharing. If it's checked on, someone is spying. Probably someone you know.
