The client had a mix of Windows XP and 7 computers in a network extended by 2 switches and a Telstra 4G modem router.The first problem was a marked decrease in file transfer speed when the client backed up large files from his machine to a Windows 7 machine they used as a file server. After performing the following tasks on the 2 relevant machinesUpdate driversRemove unnecessary Protocols eg IPv6Remove Virtual Adapters.I checked the networked adapter settings and found theSpeed & Duplex setting had been changed from Auto to 100 and therefore they were not connecting to their server at GigaBit speed. I also made the following changesEnable a 9k Jumbo Frame on DISABLE LARGE SEND OFFLOADand the transfer problem was resolved. What previously took one half hour was transferred in seconds.The other problem was that Network Discovery was consistently failing and that all or most of their available shares were disappearing.The client had 5 to 6 windows 7 machines with each machine having anywhere from 4 to 6 shares each which were used occasionally.  However they had one PC running Windows 7 Pro which they used as a  Server and which had 8 shares which were used consistently to store MYOB data, documents , graphics files etc.Windows 7 file sharing requires one PC be the Master Browser so that all Network Discovery of available shares and PC’s occurs on the Master Browser. Which PC becomes the master browser is determined by an election process that occurs at startup.I isolated which machines that could be the Master Browser by setting the registry key\\HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services \\Browser\\Parameters\\isDomainMaster to Trueon the server PC. I disabled all of the other PC’s from becoming a Master Browser except for one by setting the registry key\\HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services \\Browser\\Parameters\\MaintainServerList to NOI left the client to work in the hope we could more easily identify the problem should it arise again which of course it did. When Network Discovery failed again I could now at least identify that the problem was on the Master Browser.As Network Discovery relies on the following servicesDNS ClientFunction Discovery Resource PublicationSSDP Discovery, andUPnP Device Host servicesAnd that the following ports need to be openDNS Client requires port 53 be openSSDP uses 1900UPnP uses  5000I dropped the firewall on the server and gave the client a tool called lanclient which conveniently lists all the PC’s with shares in a workgroup and which machine is the master browser.When Network Discovery failed again it was clear there was an error on the Server as running the LanClient program produced no results.After obtaining remote access from the client to the Server PC it was clear from the event logs that there was a recurrent error on this machineThe server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.The above error had been occurring nearly daily and was the cause of the discovery problem. The fix in this case is changes to the following registry keys.Set the following registry key to 1.HKLM\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\LargeSystemCacheand set the following registry key to 3.HKLM\\SYSTEM\\CurrentControlSet\\Services\\LanmanServer\\Parameters\\Size[\/et_pb_text][et_pb_sidebar _builder_version=”4.23.2″ _module_preset=”default” header_text_color=”#FFFFFF” body_text_color=”#FFFFFF” body_font_size=”14px” body_line_height=”1em” background_color=”#0C71C3″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_sidebar][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”review” _builder_version=”4.21.0″ _module_preset=”default” background_color=”rgba(3,55,104,0.57)” global_colors_info=”{}”][et_pb_row _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” header_text_color=”#FFFFFF” header_3_text_color=”#FFFFFF” global_colors_info=”{}”]What our Clients Say[\/et_pb_text][et_pb_code _builder_version=”4.18.0″ _module_preset=”default” global_colors_info=”{}”]             Posted on Google        Leki Wangdi     Trustindex verifies that the original source of the review is Google.

Perth Computer Repairs Saved My Business!I have an old CNC machine that runs on Windows XP. When the hard drive failed, I also lost access to the obsolete software that operates the machine. I wasn\u2019t in a financial position to replace the CNC\u2014and even if I was, it would\u2019ve taken at least three months to get a new one.Thankfully, I called Digby. He came to my business promptly, clearly explained the recovery process, and outlined the potential risks. Digby managed to recover the hard drive and got my CNC up and running quickly.Since then, he\u2019s also built me a new computer and is helping with other IT-related needs.Thank you, Digby\u2014your expertise and support have been invaluable!
