Intermittent slow network browsing

Hi,
We are experiencing a weird issue with network browsing from Windows 7 x64 enterprise edition on a Server 2008 R2 share.
What happens is when a user browses a network share and selects a file, it takes +-20 seconds to select the file. If multiple files are selected it takes even longer before it responds. When it does respond, going up and down in the folder hirarchy goes
fast, but when selecting any files (not opening, just selecting) it takes very logn to respond.
While waiting for it to start responding I can open and close other programs on the PC, use Windows Explorer to browse the local hard drive all without issue. Something else that makes it weird is I browse the exact same folder and select files from another
device and I can select files without issue.
So at this point one starts to think the issue is with the local computer, but this happens with about 40 people (not everyone) but not always at the same time. And the issue is also not the local server, because it happens on two different server shares.
To be honest I'm not sure if this issue is client side, server side, network or whatever. Originally I thought network, but why does one person experience it, and the person right next to him does not have the issue? But 3 hours later a different person
has the same issue.
My gut feel is it's not a network issue, because while this happned, I ran a continous ping to the user's computer, and it did not drop a single ping, and latency stayed below 1ms the whole time.
Any deas where to start? What I've done, apart from trying to figure out if the issue is on the server or on the client, is I've bypassed the DFS-N share and accessed the share via \servername\sharename and that gave the same issue.

Hi Jacovzy,
According to your detailed description, it seems this client issue. However, we need to verify it.
Since you are in domain environment, please logon this Windows 7 Enterprise x64 edition computer with other domain user account to check if all user logon in this computer have the same issue.
If yes, it should be the client issue. We could perform a
clean boot to check if there is caused by some third-party software conflicts.

Slow network browsing (at times)

Hi all: Ever since we installed our new servers (January-February) we have been experiencing slow network performance. We currently run OES11 SP2 servers and use Novell Client 2 SP3 for Windows 7 (IR9 and 10) on Windows 7 64-bit workstations. We also use ZCM 11 SP3 clients. All our workstations are members of the same domain (functional level 2008 R2).
Here is what I observe. Right after completing a successful login access to any OES server takes 2-3 seconds for the directory list to display. Once one server has been accessed we do not see the delay to other OES server. Browsing and access to the domain servers seems unaffected. But after a few minutes and symptoms return. I have tried various remedies detailed in a few TIDS and Cool solutions but none seem to help. I have elevated the Novell network providers to the top of the provider list. Wireshark captures don't show any smoking guns.
Suggestions? Thanks, Chris.

The second thing that I recommend you do is turn off Remote Differential Compression.
From an elevated command prompt on the workstation: Netsh interface tcp set global rss=disabled
I would suggest that you try this just on one or two workstations first and see if the situation improves.
Please do let us know how it goes.
Cheers,
I may be wrong here but I just want to clarify:
From an elevated command prompt on the workstation: Netsh interface tcp set global rss=disabled
I believe this Disables Receive side scaling, not Remote Differential Compression.
To disable Remote Differential Compression you can either remove it through the "Windows Components" in Add/Remove or Run:
ocsetup MSRDC-Infrastructure /uninstall
Along with the above I run the following in a Run Once Bundle on all machines:
netsh.exe int ip set global taskoffload=disabled
netsh.exe interface tcp set global autotuning=disabled
netsh.exe interface tcp set global rss=disabled
netsh.exe int tcp set heuristics disabled

Slow network browsing in Illustrator CS3

One of our customers use CS3 on Powerpc's. They have many small files in many directories on a 2008 SBS.
The network connection is okay (copying 140 MB takes 3 seconds). Browsing tre AFP shares from within the finder is also okay. The first time this takes some time but for the rest of the day it goes fast. Only after restarting it takes a while to open the first time.
The problem they are having is opening the share from within Illustrator. Each time this takes a long time (10 to 30 seconds). First the small watch appears and then the rotating circle.
Does anybody know if this inherent to Illustrator?
Thx,
Dushan

Hi Mike,
I've tried working in groups and
also using one big share containing thousands of directories. Each directory contains apx 2 to 10 files of each less
then 150 KB.
I'm aware that on a Mac when openeing a share it also first checks the content of the subdirectories which takes time. They can live with that because it's only in the morning when opening it for the first time. After that it's okay in the finder but not in Illustrator. There must be something different between looking for files in the finder and browsing for them in Illustrator.
I've also deleted the ds_store files and used the appropiate command to avoid them being created again.
The thing that bugs me is the fact that all was okay when they used 2003 SBS. It was only when we installed 2008 sbs that it slowed down. I even installed a extremeZ-ip on the server but still the same result with Illustrator.

Slow network browsing to NetApp SAN (help)

Hey folks,
I have two location seperated by a WAN link (1Gb). I have a couple Mac's at the main location and a couple at the alternate location. The Windows 7 and XP boxes at the alternate location exhibit NONE of the problems that we are having with the Mac's. It's frustrating.
No matter if I am on a Windows box or a Mac at the main location I never have a problem. At the remote site I have problems with only the Mac's. They take sometimes two minutes or more to show the contents of a network folder. I can put a Windows 7 machine right beside the Mac and plug it into the same switch and it has zero problems. What gives?
I've tried everything I know. I've followed threads on here that recommend changing a few things in the SMB.conf file. That didn't help as I did it as well.
The Mac's are running a combination of either 10.6.8 or 10.7.x. Both Mac OS's have problems.
I'm the network admin and I have access to all of the network/server equipment including our Cisco switches and routers. I cannot find the problem. I originally
If I click on "Connect to Server" and then specify the SMB path with our without port 139 specified it will come up and prompt for credentials (on the first time only) and then open up the folder. Then I drill down through a folder or two and get to a folder that has about 4200+ pictures in the folder. Each pic is about 4 Mb in size. That is when it will sometimes take 2-6 minutes to get anything to show up.
I've tried turning of generating the thumbnail preview in Finder and that didn't help either.
Any help is appreciated.
Thanks!

Grant,
I work for an NFL team and they are game photos. Believe me, we need them and we have software that can look through those photo's like it's no big deal.
Windows 7 and Windows XP have no problems loading the content of the folders. Your answer didn't really give a solution. And no, we are not going to go through those photos and categorize them more. They are from one game. Each game has that many photos.

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.

Brand new iMac: super slow web browsing

Brand new iMac is super slow while browsing the web.
We have cable internet, and the iMac is connected via ethernet cable to an Airport Extreme router. We have a Windows machine connected to the same router.
The Windows machine loads web pages extremely quickly, the iMac takes 20 seconds to a minute to load anything.
Clearly there is a settings problem on the iMac. No idea what.
It isn't the router.
It isn't the broadband connection.
It isn't the DNS server.
Please help!

I'm not sure if you understood my original post, however, I will re-iterate it here.
I have several machines connected to the same network.
MacBook Pro
Windows machine
iMac.
Only the iMac exhibits any problems.
Clearly, the ISP is not the issue. The iMac is connected via Ethernet to the same router as the PC.
Clearly the Mac is the problem.
Changing DNS server has no effect.

IChat over slow network

Hello,
I'm not really good with network stuff, so I know very little about my problem here. I'm working on an offshore drilling rig and they've recently set up a wi-fi system for personal use. It's very slow and governed by the nanny Websense.
I know some people are able to use their IM chats and I was wondering if there is a way to set up my iChat to work on such a slow network. It won't connect at all when I'm here. I know I won't be able to video or audio chat, but I should at least be able to text chat, shouldn't I? Or is it possible that Websense has blocked certain IM's and not others?
Any suggestions would be appreciated!
Lawrence

Hi,
In iChat go to the Preferences > Account section
GO to the Server Settings tab
Whilst logged off of AIM chnage the port to 443
Log in to AIM.
This is because the regular Login port is 5190.
The AIM Application on a PC or in fact the AIM for Mac application will automatically try other ports including the web browsing port (80) to make a connection.
The port 5190 is above a Threshold of 1024 where ports have to be opened specifically. Using port 443 is below this and also used fro Secure Mail by mail applications so is likely to be open.

Login intermittently slow with ZCM agent AND Novell client

We continue to struggle with intermittently slow logins in our environment. In testing, we noticed that logins are very fast (10-20 seconds) when only the Novell Client is installed, and very fast (~10 seconds) when only the ZCM agent is installed. However, when they are both installed, logins slow down, sometimes to 1.5 minutes or longer.
We have checked DNS and rDNS, and they are both configured properly. SLP is working properly as demonstrated by the fast logins when only the client is installed. We use LDAP for user lookup, and it also works very fast to resolve user names (~ 1 second).
We are using ZCM 10.3.1, and the client is fully patched as well (both Novell Client 2 and 4.91)
Are there any specific settings (for the ZCM agent or the client itself) that might address this issue?

My apologies, I told you to remove the wrong thing.
I should have said NMAS instead of CASA.
I am just so used to saying CASA when talking about ZCM.
In regards to NMAS, you could simply rename "NWSSO.DLL" as a test.
If NMAS is installed which is tested by the existence of this DLL, then
a certain NMAS call is always made, which in some cases can take a long
time.

10.6.8 Slow SMB browsing of Windows Servers 2008

MY IMAC 21 .5 Inch MAC OS X 10.6.8 slow SMB browsing of windows Server 2008 kindly anybody have any idea why its happened or after LION release maybe this issue will be solve.

Hehe... Servers are tricky things for sure.
It sounds like you're expecting to have users log in from outside your network, but that you're testing from within? Is this the case?
If your users are trying to log in from outside the local network of the server, then you'll need to ensure that the correct port forwarding is set up on your firewall.
Next thing I'd try... Simplify your share to ensure that the problem isn't with your group set up. Eliminate all the ACL's associated with it.
Add one sole user to the ACL, give it read and write, and try to log in using that credential.
Ensure that the POSIX Permissions are set to default. (administrator should be the owner, staff should be group, read and writable only by the owner, everyone else gets read only)
If that works, remove that user, add a group to the ACL and try and log in using a user that's listed in the new group specified.
Perhaps if you supplied a little more info about your server and how it's connected to it's network. What it's roles are etc. we might be able to give a little more insight.

Force network browser to default to AFP rather than SMB?

Hi,
I'm having an intermittent problem with the network browser. When I open it, I see a list of all the computers on my network (Mac and PC). But sometimes when I connect to other macs on the network, the protocol defaults to SMB.
What I want to happen is this:
- When I connect to a PC, I want to use Samba
- When I connect to another Mac, I want to use AFP
The network browser just shows a list of aliases to all the computers on the network and presumably picks the appropriate protocol itself when you try to connect to one of them. The trouble is, sometimes I'll be trying to connect to another Mac and it will ask me to authenticate for SMB. At first I thought the problem was confined only to my mac, but some of the others on the network are experiencing the same thing.
So really, I want the Network browser to connect using AFP by default and if a particular computer doesn't use AFP, then use Samba instead. Right now, I am connecting manually using command K in Finder and typing in the IP address - which is a bit of a pain.
Any help you guys could offer would be very much appreciated
All the best
Iain

Except occasionally when the status of computers on the network change and the browser hasn't updated, you usually can expect a reliable pattern for how to connect to other computers.
The Network browser in a Finder window will group computers according to Windows workgroups, Appletalk zones and AFP Bonjour. If all AppleTalk advertisements are in the default zone, they get grouped with Bonjour AFP advertisements in the "My Network" category. Selecting a computer in "My Network" should always result in an AFP-over-TCP/IP connection (from Tiger).
Alternately, to force the issue, you can use the "Go to server..." command (CMD-K) and enter the address of the computer. If you prefix the address with "smb://" it will use SMB, if you prefix it with "afp://" it will use AFP. With no prefix, it will use AFP (it will not fail-over to SMB or any other protocol).
This is all explained in Finder help and in various documents on Apple's support site.

Whenever I try to open Network browser it gets an error.

I was trying to open Network Browser and I got this error: "Network Browser is unable to launch because your system software is not configured properly.".

After several years of use very satisfied with Firefox, recently loaded version (4.0.1) severely slows my browsing, and even my system, especially when there are pictures or videos. I said that this was not the case before and my system is Windows XP SP3.

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

How do I turn off Adobe Flash - too many sites have Flash Advertisements which slow the browser to less than a crawl.

Some pages have 3, 4, 5 or more adobe flash advertisements running at the same time, which slows the browser down tremendously. Then, if you happen to have multiple tabs open, the browser crawls to a virtual standstill, and many times, stops responding at all.
I would like to be able to choose whether or not a page can run flash content - not have it be something that runs all the time for every page, with the only option being to kill the plugincontainer process in taskmanager - which kills even the Adobe Flash items you might want to view; such as a youtube video.
Why is there not a way to turn Adobe Flash off in the browser? I have updated both Firefox and Adobe Flash but nowhere is there an option for turning it on or off depending on your needs.
Can a control be added to the Internet Options, that you can set, to have a page ask before it is allowed to run Flash Content? Having that kind of control would GREATLY enhance the enjoyment of browsing multiple pages.
Any information on how to do this, would be appreciated.

That seems to have done the trick. Thank you.
I guess it would have been too simple for it to have the same name. I was looking for Adobe Flash, whereas Firefox's add-ons manager page calls it Shockwave Flash.
Kind of hard to see an orange when the only label the box has is grape. :)
I truly appreciate your help.

(Slow Network): iSight camera not working in iChat since Leopard upgrade

I have a different type of iChat video issue. My Power Mac G4, 867 MHz, 1 GB DRAM is a supported Mac for the Leopard upgrade. I've successfully installed OS 10.5.
Also my Power Mac meets the iChat Conferencing Requirements for 1-on-1 Video Chat per the OS 10.5 system requirements and the application note here:
http://docs.info.apple.com/article.html?artnum=301050
My iSight camera is connected via Firewire to an Apple Cinema Display, which feeds back to the Power Mac G4.
1) When I boot from my 10.3.9 Carbon Copy Cloner backup my iSight works in iChat (at least locally to see myself) without any issue. Green light comes on and shows me locally on video and audio sound bars. Before the OS upgrade the iSight worked fine for live video conferences with iChat 2.1.3 under Mac OS 10.3.9
2) Running OS 10.5 when I go to iChat 4.0's preferences video pane the following message is waiting "This computer does not support video conferencing."
3) With Leopard iChat 4.0 the Connector Doctor under "capabilities" says "(Slow Network)" for 1-on-1 Video Chat and won't even show video locally or turn on the iSight's green light.

Fixed!
My Power Mac Quicksilver G4, 867 MHz. problem with (Slow Network) in the iChat Connection Doctor, no video preview or video iChat since upgrading to OS 10.5 Leopard and iChat 4.0 has been solved with the following posted towards the end of the thread below.

"NI Network Browser Error!" When Using 'DataSocket Select URL'

We have two LV 7.1.1-built executables running on two different computers that are networked together. Each executable starts the DataSocket Server on their own computer and then attempts to read from the other computer's DataSocket Server. Everthing works well if both computers are running XP SP2 or SP3.
The problem occurs when one of the OS's is Windows 2000 SP3. The executable on the XP computer can see the DataSocket items in the 'DataSocket Select URL' window on the Windows 2000 computer. However, on the Windows 2000 computer, if you open the 'DataSocket Select URL' window, and try to browse the DataSocket items on the XP computer, one of the following dialogs appears:
NI Network Browser Error!
Cannot enumerate items in this hierarchy
Cannot open a network enumeration
0x000004b8
An extended error has ocurred.
OR
NI Network Browser Error!
Cannot enumerate items in this heirarchy
Cannot open a network enumeration
0x00000035
The volume path was not found
This is usually followed by a DataSocket Read error of 214701483 (this looks like a COM object error, but for once, Google didn't have anything to say about it).
There was a similar post to this one in which Manuel Wielander suggests setting the 'Authentication Level' to 'Connect' and the 'Impersonation Level' to 'Identify'. He also suggested adding 'ole.AuthnLevel=1' to the executable's ini file. None of these suggestions work. I have also added every exception imaginable to the Windows XP firewall with no luck.
Anyone dare to step into the networking abyss with me on this one? Much thanks in advance for any help or suggestions.

Hello Archimedes,
This problem is a bit difficult to track down. I have Win 2k SP4 and WinXP Pro computers and am unable to reproduce the issue at the moment. However, I have found information that this issue has occurred in the past. In some instances it appears that changing the DataSocket Select URL.vi's Preferred Execution System to something other than "user interface" (eg. "Same as caller" or "standard") from VI Properties>>Execution resolves the problem. However, this is not a guaranteed workaround. R&D is aware of the problem and is working to fix it. I apologize for any inconvenience.
