Every time i wake my mac i get This computer's local hostname "D-360.local" is already in use on this network. The name has been changed to "D-444.local".

error message that my local host name is in use and the system generates a new one every time I wake my mac the error mssg reads This computer’s local hostname “D-360.local” is already in use on this network. The name has been changed to “D-444.local”.

There are several possible causes for this behavior.
1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local". Resolve the name conflict by renaming one or more of them in the Sharing preference pane.
2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
3. A Mac wakes from sleep due to network traffic. This is a bug in OS X that may only affect some models.
4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

Hi, this is a common problem, mostly just irksome though.
It can have many cause, like using more than one Interface for connections, Router temporarily losing x.local & seeing a new connection with x.local already used, insists it must be x-1.local, x-2.local, etc..
What all Sharing do you have enabled?
Some possible fixes...

Error after 10.7.4 Lion Upgrade to iMac
Computer's local host name .......is already in use on this network. the name has been changed to........
and it keeps adding up the number each time I wake the iMac.
What to do to get it back before upgrade error?

Ok worth repeating, hope this works. Finally spoke to AppleCare Support and walked me thru following...restart computer holding down "command" and "option" keys at the same time with letters "P" and "R" when computer turns on. This is what he called a PR restart, clears out discrepancies in memory (if that is what the error message actually is). Then went to Systems Preferences/Network/Sharing and deleted the number that kept increasing every time MAC would wake up.
Even tho this was just done, I am hopeful that error pop-up won't happen again. Fingers crossed!

Don't think this is a conflict with IP Addresses or computer names
= DHCP hangover when computer renews DHCP lease
There is no actual other computer
It just appears that way when reconnects so creates new -2 computer name
What types of names do you use your computers ?
Whether you name them after quantum particles or the romantic poets...
They will each start to be appended with "-2" then "-3" etc if you auto configure network settings from Airport Router DHCP service and you have this Change computer name issue where pop up window states name is already being used on your LAN
As stated previous post you can reset the computer name in SysPrefs / Sharing / Edit button
And restart Router or renew all DHCP leases (if persists in not allowing original name)
Can now press Edit and reset name of choice
But for Fix see link above

The name of your computer "Alpha (3376)" is already in use on this network. The name has been changed to "Alpha (6759)". Why do I keep getting this message?

I keep getting this message every time I log in. Why? I have an iMac with sharing on for my networked printer and to share file between the iMac and my MacBook. Can anyone help?

This is an annoying but not disastrous thing. Your computer sends messages on your home network and each message includes its name. If your computer is restarted or if it goes to sleep and wakes up all those messages should now gone but sometimes when the computer reconnects to the network it picks up a message with its name in it. Your computer doesn't realize its an old message from itself, it thinks the message is from a computer with the same name and that's not permitted so your computer's name is automatically changed.
Temporary solution (or not): turn everything off - your computers, printers, internet modem and router; any and all devices that are connected to your network. Then restart them. I hear about this issue all the time and this solution has been temporary for some people (days, weeks, or months) and for others it has seemingly solved it totally.

Usually this message means that you may have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. Disconnect the Ethernet cable or turn off Wi-Fi. If that's not the issue, shut down any virtual machines (Parallels, VMware, or VirtualBox) that are running. Rename the computer in the Sharing preference pane.

I keep getting a warning stating that the document could not be auto saved in pages. The file has been changed by another application. Then it says click save any way to keep your changes and save the changes made by the other application as a version, or click revert to keep the changes from the other application and save your changes to a version.
What in the heck does all that mean, and why are they trying to behave like a Windows product or a Microsoft office product. I just don't get it.
Why is another application changing my documents? It's like they've created a virus within their own programs. It's a pain in the neck and makes no sense.

I am also having the issue of a warning saying "could not be auto-saved in Pages. The file has been changed in another application. I then hit "save anyway", the warning will go away for a time, sometimes minutes, sometimes hourr, but then the warming reapprears saying the same thing. This is not the case with all Pages documents but it is the case with many.

Every time I connect my iPhone 4 to my computer to sync, iTunes stops responding. I need to shut it down and restsrt to access iTunes. I have removed and redownloaded iTunes and the problem continues.

Try disconnect your computer from the internet and see if you can open iTunes and connect your device without crash.
if iTunes does open without crash, go to iTunes Menu Edit > Preferences, "Advanced" tab and click the "Reset Cache" button, OK.
Close your iTunes.
Now, use Windows Explorer to delete the contents of Music\iTunes\iTunes Media\Download
You may now re-connect your internet then see if you can open iTunes and connect your device without issues.

Contact order: I sort first names/Last: I enter phone numbers by priority, Most used (home or mobile), then work, then fax, and save. The next time I use the phone, the order has been changed to work fax, home, mobile. Using hands free in auto is a trip

This is a pain when the phone re-sorts the order, when I need the most used number to be first using hands free in my car. Who can get this corrected in the iphone software to leave the order in which I imput numbers alone.

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

USING FORMS 6i CLIENT/SERVER
Oracle9i Enterprise Edition Release 9.2.0.2.0
When I recompile a procedure called in a form I receive the above error message. I then recompile the form and the problem is resolved.
I understand the principle behind what is going wrong but I do not recall getting this error in Forms 4.5!!
Is it my failing memory or is there something slightly more sinister involved??!!

Your memory is correct. However, Dev. 6i is not certified for an Oracle 9i Rel. 2 database. That may very well be the cause of this error. You can try the old trick of setting REMOTE_DEPENDENCIES_MODE = SIGNATURE in the init.ora file of the database. I don't know if that works on a 9i rel. 2 database though.

Mac Pro restart every time it wakes from sleep

I wonder if anyone has this problem, it is not a big one but annoying. Every time I wake my Mac Pro from sleep it restarts, why is that and can it be fixed? Or there is something wrong with this model?
Model info:
Model Name: Mac Pro
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 2.8 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 12 MB
Memory: 2 GB
Bus Speed: 1.6 GHz

It is big if the hard drive directory is corrupt in the process.
It was common when 2008 first came out, there is/was a firmware update to address this - and a long thread from March era 2008.
Underpowered UPS can also cause this behavior.

Why does iChat launch every time I wake my computer?

Very annoying. Since upgrading to Lion, every time I wake my monitors, iChat starts up. It is not in login items and I can't find anything in the preferences that suggest it should behave this way. It feels like naggy shareware, but even that would have been something I intentionally installed. I've removed all of my accounts from iChat and still it wants to start up every time I wake the computer.
I thought I had the problem licked:
http://bertrandaaron.wordpress.com/2011/12/05/stubborn-ichat-after-upgrading-to- os-x-lion/
But after my next reboot the iChat wizard wanted me to set up a new account. NO, THANKS. I just want it to stop launching in the first place. When I want to use iChat, I'll launch it manually.
Any help appreciated.

Hi,
My first thought would have been Login Items in your User Account (System Preferences > Accounts > your Account > Login Items).
Next option
Open iChat if it is not open.
You should be able to open the iChat Menu > Preferences
Go to the Accounts section.
Highlight the Bonjour account and see that it is NOT enable in the right hand pane (If the account is Ticked (in the list) it is Active )
Next place.
Lion does have this ability to remember if a window is Open on Shut down and will reopen it.
Check the System Preferences > General Section for the setting that does this under the number of Applications, Documents, and Servers that you can set to be remembered.
There is also a similar Setting in the Shut Down Message.
I would try turning both of these Off and cycling through a Shut Down and reboot sequence.
That should stop it launching on Computer Start up or Wake but it will not solve what is causing it.
Most likely it is a name that can be used in Mail or Face Time as well as iChat such as an Apple ID from MobileMe.
Also Check your Entry in the Address Book (My card = Head and SHoulders iCon) and make sure it does not list an name iChat can use.

Need to re-add Bluetooth keyboard every time after wake up?

Every time I wake my MacBook Pro up from sleep, my Bluetooth keyboard does not work; I have to re-add it via the Bluetooth preference pane to be able to use it again. This started happening a few days ago—I've had my keyboard for about a year. Why is this happening, and how do I fix it?
Thanks in advance!

I trashed the file and then after a few days had the same problems. Also, my keyboard's battery level appears to be fine. I only started having this problem over the last few weeks; I've had my Bluetooth keyboard for about a year.

Every time I turn my mac off, the desktop background changes. It always returns to the same picture, which was the second or third thing I changed my desktop to after getting my mac.

Every time I turn my mac off, the desktop background changes. It always returns to the same picture, which was the second or third thing I changed my desktop to after getting my mac. I have background switching unchecked in my preferences, and I have never selected it as an option. Also, when I go to my preferences, it will show the icon of the picture I changed it to, even though the desktop itself has switched back.

I would start with some basic troubleshooting.
