Users at my office are experiencing occasional/intermittent delays when opening and saving files to various File Shares on Win2003 Servers. I cannot determine any trend, but I am able to replicatethe issue by creating a test file on the network and edit/saving it a few times. Mostly they save immediately - the files are <1Mb - but with a reasonable frequency, there is a delay of around 30 seconds, where the Office window goes inactive (Word, PPT, Excel etc). The issue does not appear to affect XP users. I've tried the following on my machine (Dell/Win7 SP1 x64 4Gb): - Disable Offline Files - Disable Remote Differential Compression - Verify Network adapter drivers & speeds (servers & workstations) - Tried using \\server\share, DFS path, mapped drive letters etc No changes witnessed. This issue does not appear to happen when I use shares on a 2008 File Server, only 2003. Any thoughts?

Hi, 1. Please try this to disable "Large Send Offload" : 2. Open an elevated command prompt and press Enter: netsh int ip set global taskoffload=disabled 3. Disable and re-enable the network interface. 4. Run the following command in an elevated command prompt to confirm the command above is successful: netsh int ip show offloadKim Zhou TechNet Community Support

Thank you Kim, I tried the test you suggested & did not see a change in behaviour. Additionally, I would expect something along the lines of an interface configuration to have affected *all* document saves to a Network Share, rather than intermittent (but frequent) saves to 2003 Shares. It is the fact that some document saves complete near-instantly, and some take around 30 seconds (locking up the Office App during the save) that makes this issue feel a bit odd. Likewise, the fact that it is only being experienced when documents are saved to 2003 Shares, and not 2008 Shares that feels unusual.

Hi, Let us configure NTLM authentication level. 1. Click Start, type in Secpol.msc and press Enter. 2. Expand "Local Policies" and select "Security Options" 3. Locate "Network Security: LAN Manager Authentication Level" in the list and double-click it. 4. Change the setting from "Send NTLMv2 response only" to "Send LM & NTLM - use NTLMv2 session if negotiated" 5. Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients 6. Change the setting from "require 128 bit" to unchecked (No Minimum) 7. Click OK, and exit.Kim Zhou TechNet Community Support
