Explain error code 63

I am trying to control equipment via ethernet and somtimes get the error message "serial port receive buffer overflow". This stops the VI running. Could you please explain what this means.

Charlie,
the error explanation for error 63 also says "LabVIEW: The
network connection was refused by the server.". Investigate into this
error message. I guess that your LabVIEW application (TCP/IP function),
for whatever reason, looses the connection to the server while you are
communicating. The problem could also occur, when the server you're
connected too stops working.
Hope this helps!
Cheers, Stefan

Can someone explain error code DW020 - conflicts found in selected payloads?

Our laptop's hard drive failed. I don't believe Master Collection 5.5 was unregistered and uninstalled prior to the failure. I am attempting to put the software on another laptop and encounter the following errors: DS013, Fatal DW020, about conflicts found in selected payloads and flash player 10 Active X.
How can I get our license cleared up? Or what other error might I be having? Thanks.

was that exit code 6? if so, Errors "Exit Code: 6," "Exit Code: 7" | CS5, CS5.5

Where can I find Time Machine error codes?

Hi, My time machine backup keeps failing with error code 11. I can't find documentation explaining error codes, can anybody point me in the right direction?
thx!

At this point TM error codes are best known by the Apple Tech support people or at least they will have access to the software engineers who will have this knowledge. As fas as I know there's no definitive list of TM error code available to users/customers.
You can always send Apple feedback on this issue.

TS3694 Error code 3014, not explained although in heading. I could not update my iphone to OS6 as received 3014 error. Please explain or help

Hello, received error code 3014 when updating my iphone software to ios6. Click on help error code but nothing was displayed. Can anyone tell me what the code mean and how I get my iphone updated?

Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443.
Update to the latest version of iTunes.
Verify the computer's date and time are accurate.
Check that your security or firewall software is not interfering with ports 80 or 443, or with the server gs.apple.com.
Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
An entry in your hosts file may be redirecting requests to gs.apple.com (see "Unable to contact the iOS software update server gs.apple.com" above).
Internet proxy settings can cause this issue. If you are using a proxy, try without using one.

Oh ok, well that was what the test said prior to reformatting the hard drive. Now, it doesn't find any trouble no matter how many times I run it. That's what has me so confused, everything seems to check out and yet...I can't do anything, not even install the software!

DAG - Backup failing on 1 DB only with error - The Microsoft Exchange Replication service VSS Writer instance ID failed with error code 80070020 when preparing for a backup of database 'DB012'

Hi Board,
i´ve search across the board, technet and symantec sites but did not found a hint about my problem.
we drive a 2 node DAG (Location1-Ex1-mb1
Location2-exc1-mb1), on SP2 RU4 patchlevel with 40 Databases.
Since some time the backup of one - and only one DB - is failing with these events, logged on the Mailboxserver on which the passive DB is hosted.

Symatec suggests within http://www.symantec.com/business/support/index?page=content&id=TECH184095
to restart the MS Exchange Replication Service – BUT the mentioned eventID
8229 isn´t present on any of the both Mailboxservers.
The affected Database is active on Location2-Exc1-Mb1 Server and in an overall healthy state. I found during my research, that below Location2-Exc1-Mb1 Server, there are not removed shadow copies present!
This confuses me, since all Backups are normally taken from the passive copy of a Database.
So my questions to the board are:
* Does anyone is facing similar issues?
* Can someone explain why snapshots are present on the Mailboxserver hosting the Active Database, whilst the errors are logged on the passive one?
-          * Does someone know the conditions, why shadows copies remain and
aren´t removed in a proper manner?
What can cause the circumstance, that only 1 DB is facing such issues?
Any suggestion is welcome!

Hi Lenora,
I´ve encreases VSS / Exchange Backup Log levels to expert, before starting
those things i´ve all tried now:
- Backup from passive DB (forced within Symantec Backup Exec)
- Backup from active DB (forced within Symantec Backup Exec)
- Backup from passive DB without GRT enabled (forced within Symantec Backup Exec)
- Backup from active DB without GRT enabled(forced within Symantec Backup Exec)
All those attempts failed.
But brought some more details - the backup against the active DB states, that there is still a backup in progress and therefore this backup is cancelled by VSS.
The Solution was, that i´ve needed to restart the Exchange Replication Service on the Mailbox Server hosting the passive DB.
Backups are working again on all DBs!
THX for your replys.
Best regards
Markus

I get nothing but error messages, -"Your IMAP server wants to alert you to the following: 113 that mail is not available" or 364? there are hundreds stacked up.You must give answers to how to fix these when we do "search" add the error code number

I get nothing but error messages, -
"Your IMAP server wants to alert you to the following: 113 that mail is not available" or the same with: 364?
Now there are hundreds stacked up on my desktop.
I cannot find the answer anywhere. You need to give answers to how to fix these errors because when I "search" "error code" or the number there is NOTHING. NOTHING! Yet you give us these stupid error codes
then you do not give us ANYTHING on how to fix these. These error codes make me so mad it makes me hate outlook, and hate the developers and hate microsoft. How in the world can you give us ERROR codes without the explanation of what
to do or how to fix it. You need to add each error code number in your "search" then explain what it is and how to fix it. I am not a tech. I am a lawyer. I have googled the entire string of error code and nothing is clear.
So, for the last several years, I get these error codes. Also, there is another error code that won't go away--it is the password error code that asks if I want to store the password. Yes, so I say YES. but it pops back. I am sick of this. This is the reason
I hate Microsoft and I love google. #1 they respond to error, #2 them try to fix them you do not. I paid the full price to buy the OUtlook 2010, almost $500 just to get outlook, and all I got was error codes. I could not even open it because all I would get
was that error codes and NO ONE knew how to fix them. WHAT IS YOUR PROBLEM that you cannot fix the stupid error codes that you imbed? PLEASE HELP

Hi,
I understand how frustrated you are when facing such an issue, maybe I can provide some suggestions on the problem.
Based on the description, you should be using an IMAP account setup in Outlook. As for the error message, usually it's caused by a corrupted message on the Server. I suggest you logon the Webmail site, check if sending/receiving emails works well.
If you find any unusual emails that cannot be read or sent, try deleting them to try again.
I also suggest you create a new profile to setup the IMAP account:
http://support.microsoft.com/kb/829918/en-us
Contact your Email Service Provider to get the correct and latest account settings, since you have been using Outlook for years, some settings may have been changed while you haven't been informed.
For the steps to setup an account in Outlook 2010, please refer to:
http://office.microsoft.com/en-001/outlook-help/add-or-remove-an-email-account-HA010354414.aspx
I hope this helps.

Same 4MEM/9/40000000 , but different aka (hopefully) the complete guide to this error code and changing RAM

Hello world,
finally, after having been reading here for years I decided to break silence and join the most venerable Apple discussions community!
First of all, I'm no native speaker, so if I at one point don't express myself correctly, I'm sorry. If you don't understand please ask what exactly I meant since it's very important that we know exactly what each one of us is talking about, thank you.
Important, too:
I know there are a lot of posts with this topic and I sifted through a lot of them but none of them captures exactly what my problem or rather my questions are and unfortunately in a lot of them there is no real feedback from the original poster how it all worked out or not. So, I intend this thread to be that one helpful thread which more or less concentrates the knowledge of the other threads, where people with similar problems can go to in future.
I ask one thing of you: Please DON'T answer with just one phrase à la "U got bad RAM, send it back" or "Contact Apple Customer Support Service whatever thingy" without explaining why this would be the only viable option (because I think it is not, at least at the moment).
All the questions I 'd like answered are green, for you to not lose track. I hope this becomes a good discussion so everyone of us can learn a lot!
Following problem:
Initial situation:
My Computer: MacBookPro 8.2, early 2011, 15", 2,2 GHz i7; Mavericks 10.9.5    (yet without this bash fix but ¯\_(ツ)_/¯ )
       - Upgraded RAM from onboard 4 (2 x 2) GB to the "unofficially" possible 16 (2 x 8) GB
Ordered RAM on Amazon.de with the right Specs: 204 pin DDR3 SO-DIMM (1333 MHz, PC3-10600S, CL9),
Manufacturer: CSX (http://www.csx-memory.com , while it's maybe not the most renown seller, it was described on another website as reliable )
    HERE (hope the link doesn't change):               http://www.amazon.de/gp/product/B0084SH6WA/ref=oh_aui_detailpage_o01_s00?ie=UTF8 &psc=1
       - Installed it, booted Mac without problem, what does System Profiler say? I have full 16 GB   1600 MHz   Memory installed
- Obviously sent me the "wrong" RAM (or can System Profiler be wrong??), funny thing: It works,
     --> after a LOT of research checked here http://guides.macrumors.com/Buying_RAM      my i7 is 2720QM, so supports it, lucky me
   Btw, if i go to About this Mac > more information > memory, the Text there even says it can hold 1600 MHz, has this been written there like this all along?!
- Which RAM do I have installed exactly now? since the sticker on it showed the originally ordered Specs.., moreover how do I determine the CAS latency of my installed RAM?
Crashes:
Didn't really have any, except..... well,
- In some instances Firefox (I think 32.02. or sth., the latest Version at this moment) reproduceably keeps crashing, for example right now, can't even start it, that's why I can't tell you the exact version, maybe I edit that later. Safari so far hasn't crashed.
- Once I had a System Crash, but it happened when I wanted to reboot after updating the firmware of a hooked on external WD drive to be usable again as time machine backup volume under mavericks (without endangering my data).
The RAM seems to work fine; for example when I was doing a long overdue backup of 77GB on said drive, Activity Monitor showed a RAM Usage of 15,99 GB and nothing crashed. Only the fans were powering at some point but i thought that normal..
- Actually produced two more Crashes when trying to run Apple Hardware Test (AHT), the one on the second disc that originally came with my Computer (probably made for OS 10.6.x    x= 6 or sth., don't remember which version my MBP was shipped with), which leads to
Tests:
Memtest86
- I put Memtest86 v.5.01 on a USB Stick and bootet from that and let it test "the whole" RAM
(btw Do you know how you can put the bootable USB image of Memtest only to one (of a few) partition of my 32 GB USB Stick? The instructions (command line stuff) only let me put it on the whole Stick which makes it otherwise useless as a volume; ok here I'm not sure if I'm using the correct technical terms....)
- I let Memtest86 do 3 and a half passes with one pass consisting of 10 different tests, so it took over 8 hours!
--> RESULT:   0   (in words: zero) ERRORS,
--> That is why I think my RAM is ok, because I think (think NB, don't know) Memtest86 does good testing,or do you know      better?
AHT
- After that, out of curiosity, I tried to run AHT from the DVD with said results, then I ran AHT (also called Apple Diagnostics under Mavericks) from the Internet, this worked, but produced the famous 4MEM/9/40000000 Error Code,
first one for example was: 4MEM/9/40000000: 0x8477df98, the last part after the colon is variable, but stays the same in one instance, i.e. if you repeat the AHT directly. If you restart the Computer an rerun the test then it changes, e.g. some other it showed 0x84770a18
- I did the short and the extended version, it took ca. 2-3 and 16 min respectively till producing the Error Code (only 1 at a time)
- Did it 4 times or so; once in short/simple version it showed no error, the rest the 4MEM/9 s.
some example of a simple test, results taken out of the System Profiler Window (fehlgeschlagen= failed):
Apple Diagnostics:
The usual self test on start up is always passed (bestanden), see for example:
What other than bad RAM can 4MEM/9/40000000 mean? I hope there are a few tech and computer savvy people around this place who know what they are talking about and can give me a good answer, or at least help to narrow it down. Actually I also think, the RAM sticks are not loose, but before I screw open my MBP again I would like to explore the other possibilities.
Is it probable that this Error Code has got sth. to do with me installing a) 16 GB of b) 1600 MHz RAM, or maybe with CAS Latency (i don't know the actual CL of this RAM)? and if so, is it only because some Apple Programmer/Developer/Technician wrote some values in a list on the System Level, so it doesn't accept RAM it would normally work with?? If it works fine and is faster, why change it?
Final Words:
I repeat, apart from the Firefox crashes, my Mac seems to be working fine, at least I don't notice anything, (well, that disk utility and System Profiler (or whatever it's called nowadays) sometimes take time to start up is nothing special i think, is it?)
But now I'm scared that perhaps there could be a future danger for my computer I do not foresee...I hope you can at least exclude that.
So I'd rather spend my time starting a discussion here with people who don't have to abide by some corporate policy (right?) than having the hassle of repeatedly screwing my Mac open and shut and doing expensive calls with all the companies involved who won't tell me anything more in depth than "we have to send it there, do more tests and you get it back then".
I hope that this thread won't rot in the wastelands of unanswered posts and that maybe all the people who take part in it learn sth. and all the people seeking help in future will find it here.
Thanks for your patience!

Error code 265: The certificate chain was issued by an authority that is not trusted.

We are in the process of trying to set up a wireless network that uses NPS servers to authenticate domain users with computers that are not on our domain (BYOD).
We are using a valid, wildcard SSL (with intermediate certificates) to authenticate via PEAP. The certificate was issued by Godaddy.
When trying to connect, we are getting the authentication request.
The result of a connection attempt is no connection with an event log error code of - “265: The certificate chain was issued by an authority that is not trusted.”
We have tried ensuring that the certificates are in the correct containers on the respective NPS servers: “Certificates\Personal\Certificates” With the intermediate certificates located: “Certificates/Intermediate Certification Authorities”
All these attempts have proven fruitless. Any assistance or direction would be very much appreciated.

Hi,
Do you import the intermediate certificate in the right account? It should be imported in the Computer Account.
Have you imported the intermediate certificate in your client? Client need it to validate the certificate of your NPS server.
Here is a similar thread in which Greg has explained this issue in detail.

Matshita UJ-816 Superdrive: Blank CD-R / DVD-R fail to mount; Error Code 13

Greetings all,
*deep breath* This will be a long question, but I want to be thorough and informative. Sorry.
My machine is a 1Ghz 12" PB with a Matshita DVD-R UJ-816 DXJ3 Superdrive. It's basically worked fine for reading & burning all common brands of data, video, or audio CD-R & DVD-R media using Finder, iTunes, or iDVD--until now. As recently as 2 weeks ago, I successfully burned an Audio CD with iTunes (although I did get a "could not verify disc" error at the very end, the disc still plays fine).
As of last night, I can suddenly no longer mount blank CD-Rs or DVD-Rs. The same problem manifests for both in Finder: upon insertion, the standard "Choose Action" dialog box appears. When I select "Open Finder", the disc immediately ejects, and I get "Sorry, the operation could not be completed becuase an unexpected error occurred (Error Code 13)".
If, on insertion, I choose to open iTunes instead of Finder, the disc does not eject immediately, but does eject as soon as I start a new burn from iTunes.
The drive still reads and mounts burned CD-Rs and burned DVD-Rs, as well as commercial discs. Otherwise, .DMG mount fine, as do flash drives.
Here's a list of fixes I've tried thus far, which I culled from these and other forums:
- Disc Utility: Repair Permissions
- "zapped" PRAM
- reset PMU
- Delete:
/System/Library/Extension.kextcache
/System/Library/Caches/com.apple.kernalcaches (folder)
- downloaded 'Panther Cache Cleaner' & did a 'Medium Cache Cleaning'
on all Local, System, All Users Caches
- Open Firmware (cmd-option-O-F at boot-up), entered the
following commands:
set-defaults
reset-nvram
eject-cd (just for the **** of it)
reset-all
- Created a new Admin account and tried to mount a disc from there (I already had 2 accounts on my machine, both of which are Admin, but just to try)....no luck.
The only thing I know of that I HAVEN'T tried yet is a laser-cleaning disc, but I'm wary of that, since they're apparently not recommended by Apple for slot-loading drives...?
Meanwhile, there were two other issues that just manifested, which I wouldn't have thought related except that all of it happened around the same time:
1.) The latest Software Update wouldn't install. After downloading, I got
"The update 'XXXXX' [e.g. iTunes, Quicktime, whatev] could not be verified and expanded correctly. Make sure you have permission to write to /private/tmp/501/TemporaryItems/com.apple.SoftwareUpdate, then try again."
I was able to solve this in Terminal (n00b that I am) using info from:
<http://www.cybmed.com/macinblog/2004/02/software_update.html>
2.) The latest Virex 7.5 "eUpdate failed", and "try again" was no help.
I solved this by just manually d/l-ing the DAT update from:
<http://www.mcafee.com/apps/downloads/security_updates/virex.asp?region=us&segme nt=smb>.
Keep in mind that I haven't installed any new software or hardware or made any system changes recently to explain this confluence of malfunctions. Those other issues could have been coincidence, but who knows?
As you might guess, I'm well out of warranty. Furthermore, I've been reading other horror stories here from people who shelled out for a new drive, only for it to go bad just like the first one--so I really hope it doesn't have to come to that.
So, suffice it to say I'm getting quite frustrated and desperate. If anyone has further suggestions or ideas for my drive problem, I'd really appreciate it.

PS
Is it just me, or is it ironic how the drive manufacturer has "sh*t" right in the middle of the name?
12" Powerbook G4 1GHz Mac OS X (10.3.9) Superdrive: MATSHITA DVD-R UJ-816 Rev. DXJ3

Without going into a huge disertation, on this let me just say you are not the first and won't be the last that has had issues with the Matshita 816.
I did find a work around, that I will explain.
If you do a lot of burning your drive stores everything in cache files and then all of a sudden will start giving you an error message.
I found running 3 different utilitys, I run them 1 time a week need to or not and haven't got any errors since.

These all three do similar thihgs but some do different things.
Now lets talk media.
I have had the same problems everyone else has had burning 1X and 2X with some of the poor media out there.
After doing a little leg work and trying a ton of different media I have found that Maxell 16X DVD-R will burn at 1X through 16X and works very well.
Be sure to read the packaging and it will tell you this. I opt to use the 3 packs with the individual Jewel cases.(Much Better Quality).

So You try those 3 free and shareware programs and go spend 4 dollars on the Maxell discs and see if that doesn't solve your problem. I sure did mine.

External hard drive networked via AirPort Extreme gives "The operation can't be completed because an unexpected error occurred (error code -50)" roughly every two days

My lab has about 10 Mac computers. We all access a central hard drive by the way of wifi provided by AirPort. It's just a regular external hard drive (Seagate Desktop Drive) that I turned into our central storage space by plugging it into AirPort (USB). It works pretty well. We seem to be fine with viewing the file directories, opening files, saving, deleting etc., for a day or two. But then after a day or two, when when trying to modify files or move new files onto the central hard drive, we get the error message: "The operation can’t be completed because an unexpected error occurred (error code -50)"
Any suggestions as to what may be causing this problem?
All of the computers are 2011 iMacs & MacPros. The AirPort is 802.11n WiFi. The hard drive is a Seagate USB 3.0 Desktop Drive.
Thank you for your insight/suggestions.

Thanks for your reply. I agree about the communication issue. Let me explain my setup and what I am trying to do and perhaps you can answer my questions or make suggestions.
I have a MAC Mini with a Sony TV for the video monitor. The Mac Mini is hard wired to the AE (Airport Extreme). The AE has a 2 TB HD hooked up to the USB Port. I have a 17" Mac Book Pro on the WIFI Network.
I am trying to use the MAc Mini as a "Media Server" of sorts. Once I get iTunes running the way I plan I am goign to hook up my Apple TV (2nd Generation) to my television downstairs.
What I am trying to accomplish is have iTunes on all my computers look to the External HD on the AE for the files. This is why I am having my (-50 errors).
So far I have noticed that if I go and try to download from iTunes purchased videos that are not ont he computer (to the external HD) it will also occassionaly give me teh -50 error.
Is there a way to change where the files go when I download them? Say I want to download videos to the computer but not to the external HD? However I would want to still be able to move them to the External HD.

I have been exporting lightroom webgaleries to my iweb site without any problem. Suddenly I get the error message "finder can't complete the operation because some data can't be read or written" - error code -36 - thoughts?

Try this community: MobileMe on my Mac: MobileMe: Apple Support Communities.
And you can continue to use iWeb for some time to come. The following will explain:
It's now confirmed that iWeb and iDVD have been discontinued by Apple. This is evidenced by the fact that new Macs are shipping with iLife 11 installed but without iWeb and iDVD.
On June 30, 2012 MobileMe will be shutdown. HOWEVER, iWeb will still continue to work but without the following:
Features No Longer Available Once MobileMe is Discontinued:
◼ Password protection
◼ Blog and photo comments
◼ Blog search
◼ Hit counter
◼ MobileMe Gallery
All of these features can be replaced with 3rd party options.
I found that if I published my site to a folder on my hard drive and then uploaded with a 3rd party FTP client subscriptions to slideshows and the RSS feed were broken. If I published directly from iWeb to the FPT server those two features continued to work correctly.
There's another problem and that's with iWeb's popup slideshows. Once the MMe servers are no longer online the popup slideshow buttons will not display their images.

However, Roddy McKay and I have figured out a way to modify existing sites with those slideshows and iWeb itself so that those images will display as expected once MobileMe servers are gone. How to is described in this tutorial: #26 - How to Modify iWeb So Popup Slideshows Will Work After MobileMe is Discontinued.
In addition the iLife suite of applications offered on disc is now a discontinued product and the remaining supported iApps will only be available thru the App Store from now on.
HOWEVER, the iLife 11 boxed version that is still currently available at the online Apple Store (Store button at the top of the page) and those copies still on the shelves of retailers will include iWeb and iDVD.

The disc can't be burned because an unexpected error occurred (error code 0x80020000).

Hello - I am receiving this error code on all my Apple computers (iMac and MacBook) which have the most current Mac OS X 10.6.7. I'm a photographer and burn CDs frequently and out of the blue began having issues two days ago:
The disc can’t be burned because an unexpected error occurred (error code 0x80020000).
What is the remedy? Is it related to a recent update or will there be an update to fix? Since it's not simply one computer, gathering it's not the burn drive but software related...
FYI - Yes I've tried other brands of disk, etc. however, this is a part of my daily work-flow and have had no issues till a couple days ago.
Thank you all and any for your time in assisting!!
