Mac painfully slow over mixed network SMB/CIFS
I am using a Mac mini over a mixed office network. Several network operations are painfully slow. I posted a previous topic when I was using my G5 over the same network. Nothing has been resolved. G5, Mac mini or any Mac are slow over the network.
-photo previews take at least 2 minutes each to view while on a PC the whole drive of previews are instantly seen.
- Entourage common network calendar takes 5-10 minutes to view/update while the same common calender on a PC takes a few short seconds.
- Browsing folders on network drives is slow.
- Transfering files is slow
Basically any work done over the network from the Mac is tediously slow. Burning CD's and hand carry the files to other offices would be faster. The PC's instead all work fine over the network.
This looks very interesting and worth looking into. I've got the info in the hands of our net administrator.
I am making progress. I switched the mac mini from ethernet to airport. That has helped dramatically. A folder of 175 mb that was going to take hours and hours to copy to my local drive (I finally gave up) only took about 2-3 minutes over wireless. Previews of photos now happen in a few short seconds. The Entourage common calendar still takes a while to upload but that's probably an Entourage issue.
Our network administrator is going to string new cable to my office and we'll check the switching as well.
Thanks everyone for your continued help as we solve this issue and rescue the Mac's reputation in a windows environment.
This sounds alot like a duplexing issue, whereby
your macs are connecting eventually to a switch, that
isn't properly auto-negotiating your ethernet speed.
You can try going into the Network preferences and
forcing your mac to either 100 full duplex or 100
half duplex and do some testing. Some Bay
Network and Cisco switches must be set (if they are
managed switches) for fastpath operation where they
will autonegotiate better with equipment like our
Broadcom manufactured network interface cards. I
had the same issue at home with a Netgear switch, I
replaced it with a Dell gigabit switch and the
problem went away.

I'm on a MacBook Pro 2.33GHZ Core 2 Duo w/2GB RAM.
Websites are shared from a Windows XP machine using normal
built in file sharing.
In Dreamweaver CS3, opening a document takes a while. And
once it's open and everything looks good, I can click on an image
and count out 2 seconds before the image actually highlights. Click
on another image or in a table cell to type text, and it's another
two seconds.
This site website, copied to my own hard drive, responds as
fast as it should - near instant.
The website and images aren't large by any means, 43k with
HTML, images, and css. It seems weird that it'd be slower over the
network than locally. Once Dreamweaver has the document open and
everything loaded, just selecting different elements shouldn't take
a performance hit.
I didn't have this problem with Dreamweaver 8.
Anyone else having this issue? Any suggestions?
Thanks,

HP Laserjet M1132 MFP is too slow over the network!
Hi,
My HP Laserjet M1132 MFP is too slow over the network!
I have connect the printer to a windows XP 32bit SP3 using UBS port. The printer works fine on the local computer but when sharing it over the network it works too slow, for example with print test page it takes about 45 seconds to print and for other documents it takes much longer time.
I have installed the latest driver form HP website and upgrade the firmware it the latest version.
It happens on other Windows XP machines as well.
I connected the printer to my laptop (Windows 7 64bit) and it works fine (No delays over the network) and it seems that this problem have some relations with the windows XP Driver.
I have used local port trick on remote machines (instead of regular method) like this:
''add a local printer;
'new port'
'localport'
\\XPcomputer\HPPrinterName as port name
but still nothing!
There is nothing wrong with the network, we use to use a Samsung printer on the same machines over the network with no problem.
I Really appreciate your HELP!
This question was solved.
View Solution.BEHZAD_T, how is the printer connected to the network (wireless or Ethernet)? If it is slow wirelessly, I would suggest trying to connect the printer to your router with the Ethernet cord and install it to the networked computer that way.
Another question is, relatively speaking, how close to your router are the Samsung printer and the HP printer? Depending on the distance (and what stands between the devices) there can be a lag between sending a print job and it being received by the printer.
Let me know! -
Sharing Files between Mac and PC over a Network
Greetings,
I have recently made the switch to the Mac, and I have been so pleased with it ever since! I am getting married soon and my wife-to-be has a Windows XP desktop machine. I have been reading up on the different options on sharing files, and I want to ask if someone with experience can confirm what I think I have discovered.
1. A person on Windows can read and/or write to a Mac OS X formatted drive only if they run Macdrive.
2. A person running Windows XP can read files stored on a shared folder on the Mac through network sharing without additional software. But can they write to the shared volume on the Mac??
Now, I know all about the Mac side of things. It can read NTFS, read/write to FAT/FAT32, connect to Windows computers...etc. I have actually done all these things already, and know how to use them. I just want to make sure that I have the right idea before I go into working in the other direction, from Windows to Mac.
Thank you for any help that you might offer.1. A person on Windows can read and/or write to a Mac OS X formatted drive only if they run Macdrive.
You don't need Macdrive for sharing files over the network, macdrive is only needed for a PC to read a Mac formatted Hard drive that is directly connected to a PC i.e Firewire Drive.
2. A person running Windows XP can read files stored on a shared folder on the Mac through network sharing without additional software. But can they write to the shared volume on the Mac??
Yes you can write to a windows sharepoint on a mac this would be limited to their home folder unless you setup other permissions.
To setup windows sharepoints your best using a shareware utility called sharepoints
Now, I know all about the Mac side of things. It can read NTFS, read/write to FAT/FAT32, connect to Windows computers...etc. I have actually done all these things already, and know how to use them. I just want to make sure that I have the right idea before I go into working in the other direction, from Windows to Mac.
It does not matter what format hte pc drives are if your sharing over a network you only need to know about formatted drives if they are directly connected to the computer i.e firewire, or usb drives. -
Waking Mac from Sleep over the network
All, I tried to find other post on this but was unable too, so I am sorry if this has been answered already. I have an iMac G5 w/iSight camera built in, an ibook and a Mac Mini. I am trying to keep all my music, photos and videos on my imac and then share them over my local network through itues and iphoto sharing. Which works just great. But, if my iMac goes to sleep there is no way for it to be awaken over the network, at least that I can find. Is this a true statement? If I would like this data to always be available do I need to disable sleeping, or just put the monitor and HD to sleep, but not the entire computer.
Any suggestion/information on this would be greatly appreciated.

Resolving names of Mac OS clients over a network
I support a number of OS X clients (both laptops and iMacs) in a Windows-centric environment. All of the Apple systems are running 10.6.x, and are not set up to use Active Directory (although the Windows clients do). We use Retrospect for backup, which supports both our Windows and OS X systems quite well, except that we've found that the hostnames of the OS X clients will randomly stop resolving- so we've been left with entering IP addresses for many of our OS X clients in the backup system. Since we use DHCP, this can be problematic if someone leaves their computer off for a couple of days, or for laptops which are only occasionally plugged into the wired network (but we need to catch them for backup whenever they may be connected). So far there doesn't seem to be any particular pattern to this, although things seem to work more often if the fully qualified name is used (systemname.domain, even though they're not joined to domain accounts) it isn't surefire.
Does anyone else have any experience with this, and perhaps some suggestions?
As a note, this is for a medium-size division within a large organization, and we don't have any control over the network environment. We could request static IPs for every Mac system but I don't think that would go over very well. This is a critical issue, because occasionally a system will stop resolving, stop backing up, and then we'll need to access recent backup data, only to find that it's not there- not good.
I can provide any additional information needed for troubleshooting.Unless the workstations are in the same domain then you will have to open wide your Win dows domain or setup your own DNS internal server. Either that or join the Macs to the Domain.

Finder extremely slow over Airport Network after updating to 10.4.11
Hi, I have a problem with 10.4.11. Since I upgraded, about two weeks ago, I experienced an intolerable slowdown of the Finder over my Airport network. When trying to access folders and files located on my Powerbook (PowerPC G4) from a Mac Mini (also PowerPC G4) over the network the Finder stops, sometimes for minutes before opening a folder or copying a file.
When I tried the reverse, e.g. accessing the desktop Mac Mini from the Powerbook (which still runs 10.4.10) all worked fine, in reasonable time.
Do anybody have a similar problem? How can it be cured?
Thanks for helping.
PieroI have the exact same issue, and so does my sister, who has an iMac on the same network. Did you ever find a solution?
At this point, it's so annoying that I'm thinking of downgrading to 10.4.10. Does anyone know if this will fix the issue and what the ramifications of downgrading might be? Anyone know where 10.4.10 can be found? -
Transfer rate between PC and Mac painfully slow! Linksys WRT150N
Hey everyone, I have my new Macbook Pro wirelessly connected to my Linksys WRT150N, while my PC (running Windows XP SP3) is connected through wired.
I originally had dd-wrt on the router, but took it off due to the signal would randomly drop. Now that I have the original firmware back installed, the transfer rate is painfully slow. Just trying to transfer any type of media it goes about a MB per min.
Is there anything I can try to change on my Mac or my router?This is what you are after I think....

Mac OS X Server asks for SMB/CIFS Authentication

get a SMB/CIFS Authentication login window. I should get an AFS login window.
When I reboot the laptop it gives me the AFS login.

Copying itunes library from Mac to Windows over Local Network
I am a recent switcher. When I first got my MacBook I connected my Windows formatted iPod to the MacBook to transfer my purchased iTunes music, and everything worked fine.
Now I want to transfer the iTunes music folder from my Mac to a PC (both Vista and XP) over my local network. However, when I try to do this I get the following error message:
Error 0x800700FE: The specified extended attribute name was invalid.
I get the same error message if I try to transfer the individual music folders (eg Oasis).
I have no trouble transferring the folders for song/albums that I have subsequently downloaded to the Mac from iTunes. I only have the problem with the music I originally transferred from the iPod.
I have been trying to research extended attributes to see if I can edit this, but it all goes over my head. Any advice would be greatly appreciated.Hello,
i'm also a new Mac user (Vista did the trick , and i found this article on the Apple support website.
Below information can also be used to do the inverse... Mac to PC.
http://docs.info.apple.com/article.html?artnum=302392
It explains how to do a backup to CD/DVD. When you have a large library, multiple DVD's will be used.
It tried it out with a portion of my lib, burned a backup with my PC, and imported it on my MacBook. Works great! All but last played information is copied over...
Even Podcast, Movies etc are taken into account, also music not residing within the iTunes folder. After the restore on Mac, everything is properly placed within the iTunes folder you assigned.
Enjoy,
Roger

My two printers on my network (HP 8500 All in one Officejet and Lexmark Pro 805) have become very slow with processing and printing my documents. When printing, they have also made it not possible to do other applications on my Macbook until finished printing. WHat does ths point in the direction of ?
Empty your print queue of excess print jobs that didn't go through.
If you are within 1500 feet (500 meters) of someone who might connect wirelessly, make sure any wireless network you have is WPA2 encrypted, and not using 802.11b. Reboot the printers, and any routers they may be connected to. -
Mac painfully slow and freezing
Hi. I bought a Macbook about 8 months ago. Yesterday it went all slow all of a sudden - meaning 20 minutes startup time and a slow motion cursor (once it logs in and shows the desktop) with an eventual freeze after 3-4 minutes of activity (the rainbow round cursor appears and gets stuck). I spent hours researching on blogs (luckily I had my work laptop PC at home) until I was about to reinstall the OS. Then I found an article that describes how to reset the PRAM (Option - Command - P - R) - I did that and it solved the problem...
My question is - what exactly is stored in PRAM that made my Macbook completely unusable? I know my CMOS on a PC got bad but it never rendered my computer so worthless...
Second - what do I do in such cases? I was lucky to find (randomly) the solution just before I was about to reinstall the whole MacOS 10.5.8. There was absolutely no guidance or suggestion from the OS which I would normally expect...
I was very happy with my Mac for these 8 months since the music production software I used worked so very well on a Mac, but after this really bad experience I'm considering getting a PC just in case.
Thanks and sorry if this is a really basic question from a complete Mac beginnerI can't tell you what might have caused the problem. The PRAM stores certain information such as the startup volume, monitor settings, and some other system parameters. If the PRAM becomes corrupted or if there's a loss of power and the PRAM battery in the computer is dead, then the PRAM content would be lost. In some cases this can even prevent the computer from booting until the battery is replaced.
There isn't anything you can do to prevent such a problem other than checking the PRAM battery and replacing it if necessary. Of course it's very unusual for the battery to die in an 8 month old computer, so I'm guessing it was something else that corrupted the PRAM. What that would be is hard to tell other than guessing it may be a problem with the installed RAM. On the other hand it could prove to be a one time event.
There is nothing specific in the help files that covers troubleshooting. But the Apple Support site provides access to the Knowledge Base to find information that does deal with specific problems. You can search the KB using keywords to look for any relevant articles. Additionally you have access to the Discussions. Book stores also have many books about the Mac and OS X such as The Macintosh Bible and The Missing Manual. These are worth putting on your bookshelf. For more extreme troubleshooting you can visit The XLab FAQs, and you can purchase Dr. Smoke's outstanding eBook on troubleshooting Leopard. -
Sony Bridge for Mac PAINFULLY SLOW
I'm trying to sync my music to my new Z1 compact.
I'm getting write speeds of 0-100kb/s.
At this rate it might take me a whole week to sync my music.
Is this singular to me or are others having this problem?Hi FrancescoZZ,
I'm sorry to hear that you're disappointed with Bridge. We have had reports of this before, and are working on constantly improving the software.
In order for me to help you, please answer the following questions:
1. Are you using the latest version of Bridge?
2. What's your OSX version, and how much RAM does your computer have?
3. Could you provide me with error logs, which could help determine what's causing the problem?
Here’s how to get error logs from Sony Bridge for Mac:
1. In BfM, hold the "alt" key down while selecting the "Phone" menu. Select "Clear logs" to remove all old logs and get a clean start
2. Reproduce the problem you're having, whether it's connecting the phone, importing photos, doing backup...
3. In BfM, hold the "alt" key down while selecting the "Phone" menu. Select "Export logs"
4. On the computers desktop there should now be a file named "SonyBridgeForMacLogs_[date].zip
5. PM that file to me or post the contents here
Best Regards,

After a fresh install, Firefox loads websites very fast with almost no lag. After a few weeks, it becomes slower and slower. Getting to the point where it wil take aboit 20 seconds to display the Top Sites/Bookmarks window. Then sometimes opening a page, the loading circle stops moving and it freezes the phone. After about 15 seconds everything works again. The only way I found to fix this horrendous problem is to go into control panel for Firefox and Clear Data. I dont like doing that because I lose all of my bookmarks. It seems the Cache always shows "0 bytes" so there never is nothing to clear out. I would like to know where this "Reset" function is for Android. I see they have it for Windows versions..but what about Android?

Replaced 2008 DC, now remote systems are slow to browse network
I just replaced our DC that also served as one of several DNS servers. All FSMO roles were transferred to the new DC before demoting.
After doing so, the majority of our remote sites (connected via site-to-site VPN), can no longer access the UNC path of the file server also located in each remote site, and if they can, it is extremely slow. However, this isn't happening to every
remote site. Affected sites are also unable to access UNC path via IP address, although nslookup/pings resolve normally. The temporary workaround is to remove all affected systems from the domain. As soon as those machines are removed from
the domain and rebooted, accessibility to these paths returns instantly.What did you replace your 2008 DCs with?
Are you using WINS?
Transferring FSMOs wouldn't have anything to do with this. FSMOs are operational role holders that perform tasks for the domain and forest, and do not have anything to do with speed or authentication. However, I've seen slowness occur due to authentication
issues, especially with older operating systems and apps.
I've also seen issues with the TCP Chimney that can cause slowness.
TCP Chimney and RSS Feature May Cause Slow File Transfers or Cause Connectivity Problems

And if you replaced the DCs with 2012 or newer, you will also want to inventory your applications to make sure that nothing is using NTLM v1 or LANMAN, which no longer be supported in Windows 2012 R2. So if you have any older apps that are using the
older authentication methods, they may no longer work.
