Topic: Speed problem while uploading from XP to sme

[Sirio]

Hi,

i have a problem with a workstation with XP.
The network is composed by 4 machines: 2 win98, 1 WinXP Pro, 1 SME server.
The SME server is PDC and have roaming profiles activated.
Problem:
File upload (10MB) from WinXP to Win 98 = 14 sec
File upload (10MB) from WinXP to SME server = 3 min
File upload (10MB) from Win98 to SME server = 13 sec
File download (10MB) from Win98 to WinXP = 10 sec
File download (10MB) from SME server to WinXP = 30 sec
File download (10MB) from SME server to Win98 = 11 sec

I have tried:
Reset the configuration on the WinXP machine,
Create a new account on XP,
install all the patch on XP,
new network driver on XP,
SME server without roaming profiles,
reset smb.conf on SME.

No results!!!

Anyone can help me?

Thanks in advance

Sirio,

I'm assuming your logging into a domain because you have roaming profiles enabled on the server. What I would do is go into the network settings on WinXP and disable lmhosts lookup. Then reboot, or nbtstat -R . This seemed to work for me when I had a similar problem. You shouldn't need LMHosts lookup if your SME box is in client server mode on a local lan.

Thanks,
i have tried your suggestion but nothing.

Other idea?

[Ralph]

What about WINS, is that enabled, turn that off and reboot. I do remember having this problem and when I fixed it worked better than ever, what's happening is WinXP is fighting with Samba for server priority.

[Sirio]

Thank Ralph,

NO SOLUTION!!!
It's impossibile,

Update SME server: nothing
Enabling/disabling all network parameters in windows: nothing
modified various options in smbconf: nothing

i'm stuck!

Try installing the adv-workgroup contrib from James Price - it will allow you to tweak a few Samba settings from within the server-manager.

This prob is almost certainly a Samba issue.

Check your Group Policy settings on the XP box (run gpedit.msc).

BTW what version of SME/Samba are you using??

[Sirio]

Thanks Graeme,

I have tried the adv-workgroup from J. Price, but i have already tried the possible tweaks of the addon and i think nearly all those possible ones in the smb.conf.
The policy settings is OK according all the how-to from internet (IBM tutorial, contribs.org, samba), i have tried also stupid settings, like policy about outgoing packets.
It seems that one of the machine slows down the packets in some way but i don't know why!
Initially the server was SME 5.6 without update and i think samba 2.2.3, now i have patched the server with latest update on contribs.org (update4???) thinking to resolve the problem.
My next move, if i do not receive any good suggestion from this forum, is:
Step1: A new fresh installed machine with Windows XP Pro.
Step2: Upgrade the SME server to SME 6.0.

In any case this is a very strange and difficult problem!

another hint:
try to install win98 on the winXP-machine.
maybe the hardware (nic, hd, board) on that machine is faulty?

Not likely given that the OP has no problem copying to/from the XP box with Win98 at a decent speed.

i've seen speed problems when the webclient service was running in winXP.. not this severe however.

This service was introduced in winXP and aparently does nothing but slow down connections. I would also disable QOS packet scheduler if you have it installed.

[Ralph]

Sirio,

I would try a fresh install of  WinXP,  behind a firewall to prevent infection from any worms. I would disable the File and Print sharing and turn off QOS during the WinXP install or immediately after. I would then test it, you may want to try testing before any WinXP updates and right after, just to rule out any winXP update issues. if you joined the domain successfully on a local LAN, your speed should rival that of the Win98 box. One other thing, I would delete the contents of the profile folders on the server for each user, just so you do not get any strange WinXP errors.

Are you using an LMHOSTS file on your WinXP box under c:\windows\system32\etc ?..... Maybe you listed your server wrong in the LMHOSTS file?... Not much else I can think of as WinXP works wonderfully for us with 5.6(with upgraded Samba) or 6.0, with many different nics, switches, routers. I always seem to get excellent throughput, although I must say those Realtek integrated LANS are fast!...

Just testing, with SME server 6.0 and no updates of any kind I am getting about 9,000,000 bytes/sec to and from the server... for some reason downloads are actually a bit slower (maybe 8,800,000 bytes/sec)

This is with a winXP SP1 client.

I have had probs with XP on my local network, despite trying everything I could think of including re-installing the network protocols and drivers I had no joy.  I eventually tracked it down to a dodgy 3Com card, installed ok and worked, after a fashion, but was just plain broken.

Suggest you try another nic, for info, what make is your current?

I also had problems with XP network xfers, would work ok on download, but not on upload. I found that changing the "Link Speed " setting for the adapter solved the problem. I was forcing 100TX Full duplex, when I set to Auto, it uploaded quicker.

Are you using a fixed IP for the Windows machine. Necessary in my opinion for any machine providing any type of file or printer sharing.

I also assume you are only using TCPip no other protocols enabled.
